RASS (Radio Acoustic Sounding System) Station Network
Observation stations within the RASS station network transmit their observations in the form of a RASS message. Hourly observations from around 120 stations distributed globally, and the report is transmitted at 6-hourly intervals at the standard hours of observation which are: 0000, 0600, 1200, and 1800 UTC. The RASS message contains measurements of parameters such as wind speed, and temperature

Transmission of RASS messages
The RASS network uses backscattering of radio waves from an acoustic wave front to measure the speed of sound at various heights above the ground. From the speed of sound, the temperature of the air in the planetary boundary layer can be computed. The RASS message is transmitted at 6-hourly intervals at the standard hours of observation which are: 0000, 0600, 1200, and 1800 UTC. Ingest scripts run at the BADC every 20 minutes, converting the incoming files to the self describing BADC-CSV format, but neither the processed or raw data are placed into archive until the following day. The relevant parameters are stored in the MetDB dataset on the BADC website.
If you have queries about these pages or about obtaining the Met Office surface stations data from the BADC then you should contact CEDA Support. Your query should be answered within one working day. When follow-up work is required, the CEDA support will carry out the work as quickly and efficiently as possible, and in any case, the user will be kept informed of progress.
