PATHFINDER High Resolution
Surface Radiative Fluxes
Satellite observations for estimating surface radiative fluxes are presently available from several sources.
Under the joint NOAA/NASA
PATHFINDER activity, uniform long term data sets from numerous
satellites were prepared. Of particular interest are the ISCCP D1 and DX data (ISCCP). The
D1 data include observations from geostationary satellites and polar orbiting
satellites sampled at 30
km and merged into a global dataset, gridded at a resolution of 2.5
degrees. The DX data are the same 30 km observation, they are not
gridded and not merged into a global dataset, but rather, provided independently for each
observing satellite. At this Web site, long term time series of radiative fluxes based
on the D1 and DX data will be provided. The primary objective of this
project is to provide radiative fluxes at a spatial resolution of 0.5 degree
, as produced at the University of Maryland
under the PATHFINDER program. To achieve this objective,
procedures were developed to use the sampled 30 km resolution DX data,
observations from all available satellite observations, and to grid them at 0.5 degree resolution.
Auxiliary information needed for computing radiative tfluxes is
available from the ISCCP DX or from the ISCCP D1 databases, as
prepared at the Goddard Institute for Space Stdies (GISS).
