SFFILE is the name of the surface data file to be accessed.
The input for SFFILE may also be a file type. The following file
types may be input:
METAR Surface observations
SYNOP Synoptic observations
ACFT Aircraft observations
SHIP Ship/Buoy observations
SHIP6HR 6-hour ship observations
SCD Supplemental Climatological Data
FFG Flash flood guidance
NGMMOS NGMMOS model
GFSMOS GFSMOS model
GFSXMOS GFSXMOS model
When one of these file types is input, the program searches
locally for the most recent file first. If no files are found
locally, the program searches remotely for the most recent file.
The remote directories are specified in the table DATATYPE.TBL.
An optional base time may be included with the file type name,
following a bar (|). For example:
SFFILE = hrly | base time
The base time may be any valid format for a GEMPAK date/time.
Any missing parts of the date/time will be supplied by the
SFFILE may also be entered as a file template for the SFGRAM
program. The program searches for all the files with the
specified path and template.
Access to surface data in the AWIPS database is accomplished by
setting SFFILE to an alias found in datatype.tbl. Each entry for
surface data references an XML control file that needs to be
created to specify the attributes of the metadata in the database.
For example, the alias A2METAR uses the XML file
