| Upper Air Raob Data |
Standard GTS raob data have been encoded into NetCDF format and archived. Data are available at the standard
synoptic hours of 00Z, 03Z, 06Z, 09Z, 12Z, 15Z, 18Z, and 21Z.
The following variables are available in the raob dataset at mandatory levels, significant level with respect to
temperature, significant level with respect to winds, and tropopause level. Pressure, Wind Direction, and
Wind Speed are also available at the Maximum Wind speed level.

| Surface Station Data |
Standard GTS SYNOP, METAR, and BUOY surface station data have been encoded into NetCDF format and archived. Data are reported in hourly
intervals, with SYNOP reports generally occuring at synoptic hours. Some SYNOP reports fall around synoptic hours and are
listed as such. All three report types include differing variable types which may or may not be available per individual report.
