Darrell,

The sndiag program computes many indicies, and is in the current Unidata
distribution tarfile (gets built by default, the source is in
$NAWIPS/unidata/programs/sndiag). See the online phelp for more information.

Here is a quick snip from the help documentation on the
parameters computed:

    Output paramters from SNDIAG to the output sounding file are:

        HGHT    Height (the vertical coordinate)
        PRES    Pressure
        TEMP    Temperature in Celsius
        DWPT    Dewpoint temperature in Celsius
        UWND    U-component of the relative wind
        VWND    V-component of the relative wind
        THTV    Virtual potential temperature
        BVIN    Brunt-Vaisala freq / Intrinsic freq
        BVFQ    Brunt-Vaisala frequency
        RICH    Richardson number
        SCOR    Scorer parameter
        SCR1    Term 1 of the Scorer parameter
        SCR2    Term 2 of the Scorer parameter
        UCVR    Wind curvature of the U-component
        DUDZ    U-component of the shear
        DVDZ    V-component of the shear
        FLXA    Air flux across a squall line
        FLXM    Moisture flux across a squall line
        HELC    Helicity
        UABS    U-component of the non-rotated wind
        VABS    V-component of the non-rotated wind
        SHRD    Shear direction of the non-rotated wind
        SHRM    Shear magnitude of the non-rotated wind
        RRCH    Relative richardson number
        LATI    Balloon latitude (Needs RANG and AZIM in input file)
        LONI    Balloon longitude (Needs RANG and AZIM in input file)
