GOES East/West Satellite Soundings Files (23L)


GOES-12/10 satellite sounding files are available in both McIDAS and binary format, for the latest 24 hours. The files are generated hourly, and contain GOES East/West soundings over the continental U.S. and adjacent ocean areas.


GOES-East/West Soundings Binary Files

The date and time of the GOES-East/West soundings binary files are identified by the file names. The format is:
gN.YYDDD.HHMMZ, where N is 2(East) or 1(West), YY is Year, DDD is Julian Day, HH is Hour (GMT) and MM is Minute (GMT).

For example, file g2.03176.1420Z contains GOES-12 soundings for Julian Day 176 (June 26) of Year 2003, for the sounder scan beginning at 1420 GMT.

Binary soundings file format.


The binary soundings files are generated on a big endian machine. Please use the appropriate FORTRAN program below to unpack and read these binary files.

If you are running on a big endian machine:

Use the program, rdgret.f, which is available for download.

If you are running on a little endian machine:

Use the program, rdgret_swap.f, which is available for download. This version of the program will swap the byte order of the data for you.
