Global and Regional Tropospheric Year-Month Gridded Atmospheric Data from NCAR
Entry ID: NCAR_YRMOGRID


Summary
Abstract: These grid point data are from the National Meteorological Center
(NMC), U.S. Air Force, U.S. Navy, ESSPO, Climate Analysis Center
(CAC), and the University of Wisconsin, and are archived at the
National Center for Atmospheric Research (NCAR).

The data consist of sea level pressure, surface temperature, upper-air
temperature, geopotential height, tropopause parameters, u, v, and w
wind components, relative humidity, sea surface temperature, and
vorticity. Temperature and geopotential height since 1946 are given
for 11 levels; surface, 1000, 850, 700, 500, 400, 300, 250, 200, 150,
and 100 mb. Winds since 1946 are also available from 1000 to 100
mb. The sea surface temperature (SST) data date back to 1946 with
monthly grids of tropical Pacific SST supplied by Rassmusson and
Carpenter (CAC, 1982). CAC also prepares year-month summaries dating
back to 1978.

Theses data reside on a variety of grids. The earlier grids often had
a resolution of 5 X 10 degrees latitude/longitude. The later grids
include the NMC series which have a much higher resolution. The NMC
Northern Hemisphere polar stereographic octagonal grid consists of 47
X 51 (1,977 grid points) with a resolution of 381 km at 60 degrees
North. Latitudes south of 12 degrees North are omitted, as are the
corners of the rectangle. The NMC full Northern Hemisphere grid of 65
X 65 (4,225 grid points) has the same spacing as the 1,977-point
octagonal grid but it is square and extends to the equator where the
resolution is 204.2 km. The CAC summaries were prepared from the NMC
daily analyses which reside on a global, evenly spaced 2.5 degree
grid. NCAR also has U.S. Navy SST data for the Northern Hemisphere on
a 63 X 63 (3,969 grid points) grid.
