The Observation Monitoring team at the Met Office works to maintain and improve the use of observations within the Numerical Weather Prediction (NWP) assimilation of data. We do daily checks on the quantity and quality of observational data received and assimilated, and follow up any problems. Each month, we identify data that should be excluded from the NWP assimilations or corrected prior to use. We also produce statistical information on observation and model accuracy particularly for surface marine data, for which the Met Office is the WMO-designated lead monitoring centre. The statistical information is used to compile monthly Observation Monitoring reports and can also be exploited to optimise the assimilation algorithms.
