SNRAWD decodes upper air data from a file of raw data and adds
it to a sounding data set.


INPUT PARAMETERS
 
    SNEFIL    *Sounding edit file
    SNFILE    *Sounding data file
    DATTIM    *Date/time
    ADDSTN    *Add station flag
 
 
PROGRAM DESCRIPTION
 
    SNRAWD decodes raw upper air data and adds it to a sounding
    data set.

    The raw data should be included in a text file.  The sounding
    data set must already exist and must be an unmerged data file.
    The individual reports are distinguished by searching for PP
    or TT.

    DATTIM is used to specify the range of data to be included in
    the file.  Both the earliest and latest times to be included
    must be specified with the complete date/time.  If the earliest
    time is not included, data from a 24-hour period will be used.
    Since the year and month are not included in the report data,
    the year and month from the last time will be used.  Therefore,
    the data may not span months, except that data from the last
    day of the previous month will be decoded if the last time is
    the first day of the month.


EXAMPLES
 
    1.  Decode the data archived on April 26 in the file APR26.UAIR
        and store it in the file APRIL.SND.

        SNEFIL = apr26.uair
        SNFILE = april.snd
        DATTIM = 920426/0000-920427/0300
