Summary
Abstract: The National Centers for Environmental Prediction (NCEP) decodes, on an operational basis, upper air data from the Global Telecommunications System (GTS) and applies some quality controls. See Observational Data Processing at NCEP. This dataset has the data which NCEP puts in their BUFR format. Software which extracts data from the BUFR file, and places it in a basic text file can be found in BUFRdecode_ADPsfc.tar. This is a synoptically sorted dataset. more...

When stations fail to report over the GTS, or there are other data problems, we can not repair the information.

Quality WARNING: From sometime in Feb 2001 until sometime in Jul 2002, NCEP's GTS
decoder generated wind speeds which are about twice as much as they should be.
This was due to the false assumption that the speeds came from the GTS in mps
when they were actually knots. This applies to all reports except from the
U.S., Russia and ... View entire text
Access Constraints Public domain. We may distribute this data, but we do so
without providing access software, and with limited or no format documentation.

Cost: The complete dataset is not free. It is only available from the NCAR MSS.
Only users with NCAR computing accounts may download it without charge from
DSS. For all others, DSS standard pricing applies. See this ordering
information. If the user will accept unfiltered copies of whole files delivered
by FTP or written to tapes, the user will qualify for a substantially reduced
rate, aka "direct copy rate".
