TARFOX_UWC131A

This data set contains measurements made by instruments flown on the University
of Washington C-131A aircraft.  There are two types of files in this data set:
those whose name includes the letters "amb" for "continuous ambient" and those
whose name includes "bag" for "continous baghouse."  The file names also
indicate the flight date and flight number for that date.  A table describing
the instruments flown on this aircraft during TARFOX along with the parameters
measured can be found at:

http://cargsun2.atmos.washington.edu/~debbie/TARFOX/Table1.html

The files are ASCII data, with a format following the "Format Specification for
Data Exchange" developed by Gaines and Hipskind of NASA Ames.  A PostScript
version of this document is included with the README files for this data set; 
the files are named readme_tarfox_uwc131a_gaines_hipskind_1.ps and 
readme_tarfox_uwc131a_gaines_hipskind_2.ps.

The organization of the data file is shown below, using the same variable names
used in the Gaines-Hipskind specification (which are explained following the
file layout).

       nlhead  - number of lines in the file header
       ffi     - file format index, a number that (loosely) describes the
                 particular format used in the data file
                 The ffi for these files is 1010, indicating one independent
                 variable
       oname   - originator of data file
       org     - organization or affiliation of the data file origniator
       sname   - source of the measurements (instrument name, measurement
                 platform, etc.
       mname   - mission which the data is supporting
       ivol    - volume number out of total number of volumes (not used?)
                 see nvol below
       nvol    - total number of volumes required to store the complete
                 data set (not used?)
       dyear   - UT date at which the data in the file begins.  For
       dmon      aircraft data, this it the UT date of takeoff.  Format
       dday      is YYYY MM DD, all numeric.  This code stores the date
                 in three separate variables listed at left.
       ryear   - date of data reduction or revision.  Format is YYYY MM DD.
       rmon      This code stores in three variables listed at left.
       rday
                 
       dx      - interval between values of the independent variable
       xname   - name and/or description of the independent variable
       npv     - number of primary (dependent measured) variables in 
                 the data file
       pvscales- array of scale factors, one for each primary variable,
                 by which that primary variable is mutiplied to obtain
                 data values in the units specified for that variable
       pvmiss  - array of values used to indicate missing or erroneous data, 
                 one for each primary variable
       pvnames - array of names/descriptions, one for each primary variable
       nauxv   - number of auxiliary variables, variables associated with
                 a value of of the independent variable additional
                 related measurements
       auxvscales - array of scale factors, one for each auxiliary variable,
                 by which that auxiliary variable is multiplied to obtain
                 data values in the units specified for that variable
       auxvmiss- array of values used to indicate missing or erroneous
                 data, one for each auxiliary variable
       auxvnames- array of names/descriptions, one for each auxiliary variable
       nscoml  - number of special comment lines (used to note special
                 problems or circumstances concerning the data)
       scom    - array of all special comment lines
       nncoml  - number of normal comment lines
       ncom    - array of all normal comment lines
       iv      - a single independent variable value
       auxv    - array of auxiliary variable values for a given independent
                 variable value
       pv      - array of primary variable values for a given independent
                 variable value
