Observation stations within the HCM (Hourly Climate Message) station network transmit their observations in the form of a HCM message. Hourly Climate Messages (HCM), produced from automated systems such as ESAWS (Enhanced Synoptic Automatic Weather Station), SAMOS (Semi Automatic Meteorological Observing System) and CDL (Climate Data Logger), are transmitted in real time, and cover the period HH-70 to HH-10 (ten minutes to the previous hour of observation until ten minutes to the recorded hour of observation). The HCM message is transmitted from 171 UK stations, and 9 stations outside of the UK (3 in Germany, 1 in Gibraltar, 1 in Cyprus, 1 in St Helena, 1 in Paraguay, 1 in the Falkland Islands, and 1 in the Antarctic). The HCM message contains observed elements such as wind direction, wind speed, soil temperature, and global irradiation.

More Information (under review)
For more information on the observation stations and instruments used to collect measurements which are transmitted in a HCM message, the Met Office Surface Data Users Guide, describes the meteorological surface data in the Met Office Database - MIDAS.
For more information about the observation stations which transmit the HCM message, the MIDAS stations map gives the exact locations of all conforming observation stations.
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.
