SFLIST lists surface data from a GEMPAK surface data file.


INPUT PARAMETERS
 
    SFFILE    *Surface data file
    AREA      *Data area
    DATTIM    *Date/time
    SFPARM    *Surface parameter list
    OUTPUT    *Output device/filename
    IDNTYP    *STNM or STID
 
 
PROGRAM DESCRIPTION
 
    SFLIST lists any parameters which can be derived from the data
    in a surface data file.  The stations and times to be included
    are specified in AREA and DATTIM.  If no data are reported for
    a station, that station will not be listed.  The listings will
    be grouped by time.

    Conditions can be specified for the parameters.  The conditions
    are documented in the SFPARM documentation.


EXAMPLES
 
    1.  List the air and dewpoint temperatures in Fahrenheit and
        the mean sea-level pressure of the stations in Maryland for
        the latest time:

        SFFILE  =  data:newsfc.dat
        AREA    =  @md
        DATTIM  =  last
        SFPARM  =  tmpf;dwpf;pmsl
        OUTPUT  =  t
        IDNTYP  =  stid

    2.  List the same parameters for DCA, and ORD at 0900 and
        1000 GMT to the file, dcaord. Identify stations by their
        station numbers.

        AREA    =  @dca;ord
        DATTIM  =  09-10
        OUTPUT  =  f/dcaord
        IDNTYP  =  stnm

    3.  List the temperature, dewpoint, weather and cloud cover
        for stations in Maryland which are reporting any snow.

        AREA    =  @md
        DATTIM  =  last
        SFPARM  =  tmpf;dwpf;wthr=s-/s/s+;clds
        OUTPUT  =  t
        IDNTYP  =  stid
