NCEP FNL Operational Model Global Tropospheric Analyses, near surface subset, daily 1976Jul-1997Apr12
|
|
These NCEP FNL (Final) Operational Global Analysis data are on pairs of 2.5x2.5 degree hemispheric grids every twelve hours. This product was from the Global Forecast System (GFS) that was run operationally in near-real time at NCEP. DSS prepared this surface subset from ds082.0.
The analyses are available on the surface, at 1000mb and a boundary
layer.
Parameters include surface pressure, sea level pressure, geopotential
height, temperature, sea surface temperature, potential temperature,
relative humidity, snow depth (weekly, Northern Hemisphere only), and
u- and v-winds.
More information is available.
