GCOS Surface Network Monitoring Centre (GSNMC) Monitoring Products

Therefore, these data are globally collected and disseminated on the Global Telecommunication System (GTS) of the World Meteorological Organization (WMO) by special observing stations on the land surface using the CLIMAT code. Presently some 2500 stations are designated by the WMO as climatological stations (or CLIMAT stations).

It was decided that the operational exchange of the GSN temperature and pressure data via CLIMAT messages on the GTS be routinely monitored. The proposed tasks of the GSN Monitoring Centers include monitoring the availability, timeliness and completeness of the CLIMAT messages distributed via GTS to improve the performance of the GSN, and performing basic quality control and assurance procedures for GSN stations to obtain high quality and completeness of the data set.
