Budget (SRB) Data
Access to the
This is a first attempt
to provide the user community with surface radiation budget (SRB)
data, as generated by the National Oceanic and Atmospheric Administration
(NOAA), National Environmental Satellite, Data and Information Service
(NESDIS) over the United
States. This activity is in support of the Global Energy and Water
Cycle Experiment (GEWEX) Continental
Scale International Project (GCIP)
and GEWEX Americas Prediction Project (GAPP).
The product is an
outgrowth from an ongoing activity at the Department of Atmospheric and Oceanic Science,
University of Maryland to develop and validate an operational model
for deriving surface and top of the atmosphere shortwave radiative
fluxes from Geostationary Operational Environmental Satellites (GOES),
in support of GCIP activities and regional operational numerical
weather prediction models.
daily, and monthly mean information on surface downwelling shortwave
(SW), top of the atmosphere downwelling and upwelling radiative
fluxes, photosynthetically active radiation (PAR), cloud amount,
and surface skin temperature are provided for an area bounded by
70-125 W longitude and 25-50 N latitude. Validation results against
ground truth are also included.
Three types of archives
The current data archive
provides information within one to two days of real time. At the
completion of the current month record, the data are moved to the
historic data archive. Historic data are currently available from
1996 to 2006, and past months of 2007.
