FNMOC NAVDAS-AR Observation Impact Monitor

FNMOC NAVDAS-AR-NOGAPS OBSERVATION IMPACT MONITOR

This NRL page is used to monitor observation impact on short-range forecast error. The products are produced using adjoint versions of the NRL Atmospheric Variational Data Assimilation System - Accelerated Representer (NAVDAS-AR) and the Navy Operational Global Atmospheric Prediction System (NOGAPS).
