North Atlantic Hurricane Region Hybrid Coordinate Ocean Model (ATL-HYCOM)
Forecast Model (FM)

In order to have the substantially different physics and truncation eddors (as shown in the below plots) required for a credible OSSE system, along the configurations substantially different from the NR, the FM uses the climatological Atlantic HYCOM analysis which has the 0.08ogrids in horizontal and the 26 hybrid layers in vertical.
