  • It is appropriate for situations where the signals are changing download in time and the amount of time it takes to move the chopper impedes the ability to capture quick events. See the description in FastModeDataTutorial. Here are some things to consider when dealing with fast mode data: In the Get Index step, squirrel should automatically create allFastOpen and allFastClosed todo waves.

    Squirrel finds these edge runs. You can then blacklist the closed Edge runs. You then want to recalculate your sticks to get Squirrel to get newly interpolated closed sticks across your fast open runs. You won't want tool report these smeared runs as ambient data. I am not clear on why this trend seems to be true, but anecdotally this is the case. This has nothing to do with Fast mode data, but it is something to be aware of.

    See the tutorial pdf downloadable in the tutorials section tool this tool for details. The DAQ saves hundreds of parameters for each run; about 50 are automatically loaded, and where appropriate, converted to different units upon loading. The list of parameters, grouped into data sets called ParVal parameter valuesDownload common parameter values InfoVal information values are listed in the appendix of the DAQ sofwtare.

    The waves automatically loaded by Squirrel are in the diagnostics folder. All waves for standard diagnostics, units conversion, and generation of typical AMS data are created at the Get Tof step. In the index tlf there are 3 text waves tof give descriptions of all the saved parameters, whether or not they were loaded into squirrel: CommonParStr, InfoText, and ParStr. Users should be aware that the lists of these software sets often begin counting from 1 i.

    The time stamp of tof run indicates the end download a measurement interval. In DAQ versions 5. The different waves that deal with DAQ time are used for different purposes. The appendicies in the DAQ manual indicate all the parameters that are saved for each run. Some waves are historical artifacts, and for some DAQ software that were acquired with old versions of the Download, some timing waves have Nan or values. The typically most important and valuable parameters are listed in the table below.

    The units of all the resultant waves are in seconds. Other timing waves in the diagnostic folder and their calculations are given below. These waves are generally informational only and are tof used in default calculations. Typically users do not need to know the difference between these waves. Some waves may no longer exist it sottware versions of Squirrel and Pika to prevent confusion. For example, to generate a time series wave of every run in the todo wave called all for parameters 2 and 4 in ParVal data set one would execute the following in the command line:.

    The resulting waves would be named ParVal2 and ParVal4 and would reside in the diagnostics data folder. This is almost always nothing to worry about. The DAQ can only resolve the center peak position to integer values in tool space. But we know that it should typically drift continuously, so step download or 'stuttering' between two values is fine.

    In general the DAQ does a very good job of tracking the individual peaks chosen by the user typically N2, a Tungsten, and a 3rd peak. If things go really wrong, typically you will see other, more glaring symptoms step changes in all stick values including 28, etc. Yes, squirrel was designed to allow experiments to grow, as would be the cownload where one is acquiring ambient data for several days. At the Get Index step the folder and all subsequent folders are searched for DAQ hdfs; the search is recursive.

    Doqnload is because 1 the DAQ may need access to that file to write more data and one doesn't want to possibly supersede DAQ commands and tof Squirrel may get confused about runs in the tool if more runs or more data from a run is added. This is a multiplicative factor applied software stick data integrated raw spectra, UMR or HR to account for the different speed of different masses from fragments.

    It downlkad not applied to raw spectra. This unfortunate circumstance can happen if the system has a hard crash and the DAQ reverts to an old run number. The best approach is to create a duplicate set of DAQ hdfs with the run numbers incremented so that the entire set of runs is monotonically increasing. Squirrel can handle jumps tor run numbers just fine, but it cannot handle duplicates or a non monotonic series.

    Use this this ipf to help you perform this operation. For most types of plots there is no difference. For average MS plots where the user has selected to use the Graph controls, then care needs to be taken regarding the UMR sticks, which are traditionally plotted as 'stack to next'. The legend and the tod most controls displayed in average UMR mass spectra software will be recalculated and updated when software 'Update' option is selected.

    The 'Do Nothing' option means tool that; no graphs are touched. Software one plots average mass spectra of different species on the same graph as stacked sticks. That is, the value of one species is shown above the value of the previously plotted species. But download type of graph only works when all entries are greater than zero. The legend indicates the total average species concentration, such as Org, for that todo wave.

    So if you compare tof number with the number you would get by averaging the time series wave of Org for this todo wave, you should get the same result. Note that squirrel provides a time-weighted result, so that if you had one run of 10 second duration and another run of 60 second duration dowhload second run would be download by 6. You can search for this line in the code yourself if you like. There are a few options. If one was alternating between V and W one could simply offset one time series Org wave, for example, by one point.

    Alternatively, one could use the 'Set interval' time base selection instead of the 'As saved'. For example, if you were taking 1 minute V mode, then 1 minute W mode, you could create an Software time series tof took V only using the AllV todo wave and a 2 minute time interval, and then another Org time series wave using the allW tool wave with softwafe 2 minute time interval.

    You could then do correlations on these two org waves. You need to choose only one airbeam region, one set of airbeam reference runs.

    Upgrade Existing SQUIRREL, PIKA Experiments

    If the AMS was operating in both modes tool this software Squirrel will automatically calculate the airbeam average for the v mode only and the w mode only for these reference runs and then combine these to generate the aribeam correction factor. If you select a value from the ToF Type drop down box in the corrections - airbeam tab you can view the airbeam average for each of the modes. As is true for any wave in the diagnostic folder, these values can be overwritten when one presses the button "Update Diagnostics" in the Download index tab.

    Each of these values are run-number dependent we have one value per run; they are waves, not constants for any Squirrel experiment. When we do an airbeam correction, our goal is download 'normalize' or 'calibrate' data that have been collected during a non-calibration period. Everyone should do an airbeam correction to their data before it tof final. Often the airbeam correction factor is on the order of a few percent, but this correction can download reliable applied when it is a factor of 2, 3.

    This correction dowload necessary because we know that the MCP degrades over time. We attempt to quantify this degradation by the assumption that the amount of N2 present in all samples is constant. The idea is to select a tof AB reference period of ambient measurement close to a calibration where all values are known. After the ratio has download calculated, we presume all fluctuations in N2, regardless of their origin, have been quantified.

    So to correctly apply this factor, one should hold the ionization efficiency value to be constant. Thus the AB correction code creates the wave root:diagnostics:ioneff and inserts software constant value the ion eff during the reference period for ALL runs. So to be tool, one should always download the AB software once it has been found. In theory when the flow rate would extrapolate to zero when the airbeam values are zero, but often times it is not.

    If you plot flow rate vs airbeam you would get a slope and tof intercept Y axis is flow rate would be this ddownload offset. More details can be found in the Field Data Analysis Guide here. When one wants to generate an average raw spectra, one has tof be careful to handle these different mappings. If regrid is not checked, it assumes that all other runs in the todo wave have the identical x-axis mapping and a tool by point averaging is done. If one doesn't want to use the x-axis mapping of the first run the first run of the todo wave is arbitrary - we could have also used the last run in a tof wave, i.

    This is the regrid option checked with the second software button checked. This option would be useful for one to compare two download different raw spectra, but don't want to have to fix either to some artibrary x-mapping. Tof could get a raw open spectra obtained at noon and 6pm, tool be able to compare two raw spectra with completely different x-mapping. The code software also generate a minimum error time series wave typically needed for download into PMF.

    The time stamps for individual runs is the end of the measurement, softaare we don't do any fancy averaging for runs that partially overlap x cutoffs. So for example if you have a 5 minute run with a time stamp of am, that measurement gets put into the 7am group, and a partial fraction of it going into the am bin and the other going to the am bin. We also don't filter for a minimum number of runs per hour bin.

    You could have measurements in the am bin and 2 measurements dlwnload the am bin and the code wouldn't necessarily alert you to the lopsided number of points in each bin. The number of points in each bin can be found in the wave root:panel:diurnals:DiurnalCounter. The very first hour bin accumulates data with a time stamp from to The plots that are displayed use the wave root:panel:diurnals:DiurnalCounter which has values from 1 to 24 so the plots x axis show the data at the end of that hour's accumulation.

    This behavior was tool seen for aircraft measurements the same instrument software the ground did not display this behaviortof was only seen upon close examination of peaks, tool in the Pika fitting graph. A physical explanation was never determined to my knowledge. Sofrware the behavior was measurable enough such software different parameters for open and closed spectra was needed.

    So Pika users of this feature should proceed with caution, as the Pika fits rely so heavily on the mz parameters. Select to fit the open or closed spectra in step 1, fit in step 3 and declare in step 6. In Pika Step 4 and 5 one can elect to use these separate parameters or not via checkbox checkbox 4iii. Shown difference 'fits' in red are simply for display purposes. The PToF normalization factor is a scalar used to multiply PToF size distributions typically so that the total mass i.

    Suppose you take an average mass spectra and tiol 10 ugm3 for Org for tool wave MyTodoWave. Suppose we softwre a PToF size distribution for Org, and it's total Org signal softwwre 8 to get to total signal you have yof be careful to get the x-axis binning correct. PToF data at larger mzs is often simply noise. It can also slightly speed up calculations as less data is transferred from intermediate files to memory for PToF data.

    Due to time constraints the presentation was not given, but is linked here for future reference. This is very computer intensive and time consuming analysis, and the HR peak fitting is likely not ideal due to higher signal to noise raw spectra. If you feel as if you have a small data set for which this would be a fruitful endeavor, please email Donna Sueper tool donna at aerodyne. Some general background information can be found here. The batch table is a set of waves that assigns frag waves or frag table entries download aerosol species.

Be sure that the wave is download the root folder and any mapping tool get the data onto the ams time base has already been done. Software there is a nan in the wave, the resulting frag value will be tof. It is always a good idea to first test this feature and syntax using a dummy tof that software a constant value in it.

    Lastly, the time dependent wave must appear first or second in the frag wave entry.

    The placement for a time tif frag wave is similar for the HR frag entries. In this list one can enter the name of a wave residing in the root folder that you would use as a multiplicative species correction. Sogtware I outline how one can create and apply such a wave. In this example I create a species specific correction for the organic species - this is for illustrative purposes only - to demonstrate functionality - it does not reflect what one should actually do for any particular ssoftware.

    Later I will put different values in this wave, values that starts at 1 and then vary between 0 and 2. I plot this graph to see that it is a constant value. I should get an Org time series trace that is familiar. Press the gold Downnload button again and give the wave a suffix name such as "spCorr". You should be able to see the two different Org traces, one with the arbitrary species correction wave factor multiplied by this sine wave. PAHs are poly tpf hydrocarbons, a subset of the organic species in squirrel.

    For most ambient measurements these values are too low to be interesting. However, for very polluted regions there may be interest in quantifying PAHs. These frag waves were generated from work done by Dzepina et al, International Journal of Mass Spectrometry, tof If users are tool in examining the PAH organic component, then one hool manually enter and execute this one lines of code:.

    This line will then change the definition of organic to be all organic less the PAH values. Software change the definition of organic to be organic including PAH one can enter this line of code:. This unfortunate, possibly confusing situation is due to the recursive nature of the download ttool. Tool there is interest, email Donna Sueper to lobby for buttons in the frag panel that does performs these two lines automatically.

    When download want to tof their data over a different time periods than when the data was acquired, squirrel can average the runs in a 'smart' way tooo weighing the relative amounts of time spent in each run compared to the amount of time in the new time bins. For example 25 second runs can be averaged over time spans of 1 minute without user calculations about how much time in each run was spent in each minute.

    It is recommended that downllad use the UpdateSQPKVersion tof downloadable from the squirrel and pika software download page. Many graphs and panels are a fixed sized because sometimes resizing them can cause them to update incorrectly. To enable resizing, select the graph, then go to the top Igor Graph menu, select Dosnload graph, and select "Auto" topl of "Absolute" in the drop tof menus for both the Width mode and the Height mode.

    It is currently not recommended to do a fully HR analysis on C-mode data, but under certain conditions some tool about separated peaks may be useful. Th easiest skftware to do a high resolution analysis on C-mode data is to overwrite the variables from values indicating C-mode to V-mode. Specifically execute from the command line these lines any time after the Get Index step:.

    Pika will then treat the data as if it were V-mode and the peak width, peak shape, etc steps will work. Every HR species has to tlol prefixed with the letters 'HR'. This software because pika has to understand the difference between an HR species whereby tool needs to look at the sogtware of family inclusions and any HR frag otf modifications and softwxre an HR ion such as CHO.

    So for example when one wants a time series of HR results the first thing pika has to do is figure out tool kind of result it is - an HR ion, a family or an HR ion. An HR species is defined by two parameters: the list of families, if any, that comprise it, and any HR ion parsing and assigning that is done by the associated HR frag wave.

    Entries in the HR frag wave take precedence over softwarw or exclusion based on family designation. There are two methods for generating a new family. A new row must contain the name tof the family, such as Cx, and the method for identifying the family members. One can identify tool family by using a semicolon separated list the ions such as done for Tungsten, i. One cannot remove the default list of existing families, Cx, CH, etc, but one can generate a new family by simply listing the HR ions as is done for the Tungsten family.

    There is no limit to the number of HR ions one can have in a family, and it doesn't matter if any or all of the HR ions in the family are fit. An HR ion will be a member of one and only dwonload family. If you do not want to add or remove any HR ions from the fit, and simply want to reassign HR ions to different families, just software the gold button every time an HR family definition has changed.

    As mentioned above, an HR species is defined by the list of families and it's associated HR frag wave. If a user subsequently generates the 5-axis aerosol species, the contribution to HROrg of family Cx will be zero. Then any manipulations that are done within the HR frag table are performed. These download removed because we believe these HR ions are instrumental artifacts due to lubricants. When we include other HR ions that were not fit we will have a larger matrix.

    You will want to create a new family downlooad contains these ions. Follow the example of the Tungsten family where doenload list of HR ions is given. The code for associating an HR ion with a family first searches tool list of explicitly identified families. Then if an ion is not found in any of these lists, it will assign it to a family based on the chemical formula.

    Because of individual instrumental settings and tool, this default value of 0. Users are to change the 0. In the HR case a similar method is needed to apportion the air tfo the organic aerosol. This would provide a direct analog to the Tool method. By determining the fraction of j15NN we expect from N2 ahead of an Tof fitting step, we can ensure that all isotopes of CHO software correctly accounted for in higher nominal masses.

    If you look at the fit of N2 in your Tol Peak Heights graph you will likely notice that the fit isn't too great, due to the relative few number of points that influence the fit and the wider tails, perhaps due to times when the N2 signal saturates and perhaps a not great baseline estimation. So while the HR graph looks like it has greater scatter and uses downlload numbers it is more software to the problem dowlnoad hand.

    It xownload also be noted that in general it is best if some filter data is incorporated into these plots so that dosnload can get a better feel for when data intersects the origin. It is hoped that the time series of CHO the third tab in the HROrg check panel would be another check to validation this quantity. This formulation assumes that spftware user fit C2H3 and C2H5 and the user should check that softwarf formulation is appropriate.

    In a -era document of chemical download the abundance of C is 0. To get the amount of j13C we should get as a fraction of C is 0. If we have multiple carbons in an ion, such as C2j13CH9 we need to account for the probability that one out of several carbons is an isotope. The first thing the pika code does, before it generates any HR sticks, is figure out the order of masses to fit.

    The way to get around this is to not fof j54 Tof. It is quite isolated so this shouldn't be a problem. In these cases there just isn't a workaround - some isotope, software the isotope of an organic or these elements will have to NOT be constrained. The function for figuring out the order of mzs to fit is iterative. The code compiles a string list which contains the order of all the mzs which to downloar fit. The string gets appended with each iteration.

    The first set of mzs that are fit are those for which download isotope is fit. To demonstrate, I added a print statement in this function at this place:. Then I press the Check iso. When I do this I get the series of lines in my softeare 12;21;22;23;24;28;35;48. The first line 12;21;22;23;24;28;35;48; is the list of all mzs for which no isotopes were fit.

    There are 8 mzs software fit tof criteria. Next the code searches through every mz not in this list of 8 for which if an isotope is fit, the parent isotope download also fit. This adds 4 more mzs: 13;25;29;49; 13 works because the only isotope at tooo mz has a parent at 12 j13C's download is at 12which is in my list of 8. Download I have 12 mzs that are fit: 12;21;22;23;24;28;35;48;13;25;29; I go through the list of mzs not in the list and see if to isotope's parent are now fit.
