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.

 All the maps are interactive and extra information on the specific station is shown by hovering on the markers.
