DAE diagnostics

DAE Diagnostics

DAE (Data assimilation and Ensembles) diagnostics provide a complementary data quality assessment to real time monitoring of satellite observations. These diagnostics provide information on the capacity of observing systems to reduce analysis and forecast errors (so-called ‘forecast sensitivity to observations’ (FSO) diagnostics) and allow users to compare observing systems and identify data that could be detrimental to the quality of NWP forecasts.

Currently the NWP SAF offers web-based DFS (Degrees of Freedom of Signal) diagnostics which measure the relative impacts of different observation types.
