ASCII Surface Data File

This type of file is generated by the surface METAR/SAO decoder (sfcdec) and the synoptic decoder (syndec) programs for use with other WXP surface display programs.

FORMAT

This is an ASCII format which makes the files editable by programs such as "vi" and "emacs". ;The format of the file is as follows:

WXPSFC
hhZ dd mmm yy
iii TTT ddd wwww aaa ppp vvv hhhC[,hhhC...] WWW [@tttt] [LAAAA,OOOOO] [PTttt][QRRR] [rrrr][qrrr] [RRRR] [Xxxx] [Nnnn] [Tee] [SSS] [Cccc] [Ggg] [ssss] [#cccccc...] $
iii TTT ddd wwww aaa ppp vvv hhhC[,hhhC...] ... $
...

Header Format

The first line of the file is the string:

WXPSFC

which is used to determine file type. The second line of the data file contains the date and time in the following format:

hhnnZ dd mmm yy

Where:

Example: 21Z 1 MAY 20

Data Line Format

The data are entered on the following lines, one station per line. Each particular piece of information is separated by a space and the line is terminated with a space and a "$". The format for each station is listed below:

iii TTT ddd wwww aaa ppp vvv hhhC[,hhhC...] WWW [@tttt] [LAAAA,OOOOO] [PTttt][QRRR] [rrrr][qrrr] [RRRR] [Xxxx] [Nnnn] [Tee] [SSS] [Cccc] [Ggg] [ssss] [#cccccc...] $

Where:

EXAMPLES

Example of raw surface data:

KEWB 011153Z 18014G19KT 1 3/4SM RA BR OVC006 12/12 A2980 RMK AO2
     SLP089 P0013 60059 70059 T01220122 10122 20117 55009=

The above line would be decoded into the following format:

KEWB 540 540 1814 980  89 1.75 6O !RA_BR @1153 P5 -9 r59 R59 x54.0 n53.1 G 19 #AO2 P0013  $

A sample surface converted file would look like:
