MSAS/RSAS

Surface data is crucial for mesoscale weather forecasting because its time and space resolution is unmatched among in situ observations. The Mesoscale Analysis and Prediction System (MAPS) and the Rapid Update Cycle (RUC) Surface Assimilation Systems (MSAS/RSAS) exploit the resolution of surface data by providing timely and detailed surface analyses. RSAS (also known as the RUC Surface or "RUCS" system) runs operationally at the NWS's National Centers for Environmental Prediction (NCEP). MSAS runs operationally at NWS Forecast Offices as part of the AWIPS workstation, and contributes quality control information to the Quality Control and Monitoring System (QCMS). RSAS also runs quasi-operationally in the FSL Central Facility to provide an operational backup to the NCEP system.
