GRAS Meteorology SAF is a EUMETSAT-funded project that develops an operational radio occultation system responsible for delivering refractivity, temperature, pressure, and humidity profiles in near real time and the ROPP software package for numerical weather prediction models and for carrying out related research.

The GRAS SAF Leading Entity is the Danish Meteorological Institute (DMI), with Cooperating Entities ECMWF (European Centre for Medium-Range Weather Forecasts) in Reading, United Kingdom, IEEC (Institut D'Estudis Espacials de Catalunya) in Barcelona, Spain, and Met Office in Exeter, United Kingdom.
