PALMS aerosol composition for diam 200 to >3000 nm.
Sampling alternates between aerosol inlet and CVI (cloud particle) inlet.  Only aerosol inlet
data products are reported here.  Typically the PALMS size range spans the peak of the aerosol mass mode.  
Single particles are classified into the particle types shown below.  Number fractions of these particle
types are calculated over each time segment, and these averages are presented as the primary data products.
Some additional chemical data products are also given.  PALMS alternates between positive and negative
ion detection mode, which yields different data products.  If there were at least 5 suitable particles 
in a time interval, average values are calculated.  The number of particles used to calculate the averages
is also reported.  Other data products, including size-resolved composition, are available - contact the PI.

  ***Positive ion mode data products:   SeaSaltFrac, MineralFrac, SootFrac, BioBurnFrac, SulfOrgNitFrac, OilCombFrac, UnclassFrac
The sea salt fraction (0 to 1) is the number fraction of particles that are identified as sea salt.  Likewise for 
particles identified as mineral/meteoric/metallic, soot, aerosol from biomass burning, sulfate-organic-nitrate internal mixtures, 
heavy oil combustion (Vanadium tracer), and unclassified particles.

  ***Negative ion mode data products:   SulfMF, OrgMF
Averages are given for sulfate and organic mass fractions (0 to 1).  These parameters are calibrated quantities and are only 
calculated for particles that are sulfate-organic-nitrate internal mixtures (which is often the predominant particle type).  

  ***Acidity data product:   SulfNeut
This is the average degree of sulfuric acid neutralization calculated only for particles that are sulfate-organic-nitrate internal mixtures.
It is reported as the ammonium-to-sulfate ratio, NH4:SO4.  This calibrated product becomes insensitive to the degreee of neutralization
for highly neutralized sulfate.  Values >=2 are therefore not quantitative but nevertheless indicate complete neutralization.
