GEOS Near-Real Time Data Products

GMAO generates GEOS data products in near real time or reanalysis modes in support of diverse user communities. Starting in February 2013, GEOS forward processing is conducted in two separate streams. These are called (1) Forward Processing (FP) and (2) Forward Processing for Instrument Teams (FP-IT). » Read More
