Near real time validation
- For early detection of possible problems with satellite based
retrievals of Surface Radiative Fluxes, timely comparison with
ground observations is important. Capabilities were developed
and implemented to use the six SURFRAD stations (Penn State, PA;
Desert Rock, NA; Goodwin Creek, MS; Boulder, CO; Bondville, Il;
Fort Peck, MT), to perform close to “real time” evaluation of
satellite estimates against these observations. On the average,
the SURFRAD data are available within three days from observation
time. This time interval was selected for providing the evaluation
results on this Web site. Comparisons on hourly time scale, representing
the diurnal cycle at each location, will be kept on this WEB site
for one month.
- At the end of a one-month period, scatter-diagrams of hourly
observation and relevant statistics for each station will be provided
and kept on the Web site, for reference.
The objective is to provide results from ongoing evaluation activity,
using observations from numerous available data sources, known to
be of good quality. Due to the large amounts of data involved, and
the different distribution time schedules of such data, only “historic”
presentation of results is possible.
