Nogaps Atmospheric Model

The Navy Operational Global Atmospheric Prediction System (NOGAPS) is a spectral general circulation model (GCM) which has been under constant development at the NRL over the last 20 years. It is the principal source of atmospheric forcing for the US Navy ocean models (eg. NCOM) and short term numerical weather prediction (NWP). NOGAPS uses a one way coupling system to capture ocean-atmosphere interaction. NOGAPS has global coverage, with horizontal resolution ~1/2°. The forecast length of the NOGAPS product is 144 hours with temporal resolution of twelve hours (at 00 and 12 UTC) and updates at 06 and 18UTC to enable background forecasts, which are used in the analysis. Outputs from the model include momentum flux, both latent and sensible heat fluxes, precipitation, solar and long wave radiation and surface pressure, as well as 10 metre U and V wind velocities (Rosmond 1992; Rosmond et al. 2002).
