DSS presents a surface subset of the Global Final (FNL) Analyses on a pair of 2.5x2.5 degree hemispheric grids, every twelve hours. These were operationally prepared by NCEP. The NCEP documents About the Global Parallel System and EMC Model Documentation describe the model.

The analyses are available on the surface, at 1000mb and a boundary layer. This subset was prepared by DSS from the analyses in DS083.0. Parameters include surface pressure, sea level pressure, geopotential height, temperature, sea surface temperature, soil temperature, water content of soil, ice cover, water equivalent of snow depth, relative humidity, specific humidity, u- and v-wind components, minimum temperature, maximum temperature and land-sea mask
