Observation stations within the HSUN3445 (Hourly values of SUNshine duration from Metform 3445) Station Network transmit their observations in the form of a Met Form 3445 message. Many stations with autographic or other recording instruments provide analyses of hourly values for climate purposes and the data are usually returned on Met Forms at the end of the month. The sunshine observations are returned on the Met Form 3445 from 73 observation stations worldwide, 69 of which are in the UK. The HSUN3445 message contains sunshine duration measurements.
For more information on the observation stations and instruments used to collect measurements which are transmitted in a HSUN3445 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 HSUN3445 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.
