The maps linked in this page are produced with a statistics of the last 7 days of data acquired at ECMWF by the SAPP (Scalable Acquisition and Pre-Processing) system. The aim is to provide a detailed picture of the observations data coverage and issues in terms of data format to give a view from the NWP perspective of the status of the TAC to BUFR migration.
