GNSS radio occultation L2B temperature, pressure, and water vapor retrieval for METOP as contributed by ROMSAF, version 2.0 (gnssro_metop_romsaf_l2b) at GES DISC

This dataset provides Global Navigation Satellite System (GNSS) Radio Occultation (RO) Temperature, Pressure, and Water Vapor data from the Meteorological operational satellite - A (Metop-A) mission as contributed by the Radio Occultation Meteorology Satellite Application Facilities. Each granule represents a single occultation.

GNSS RO is a remote sensing technique that measures the refracted radio signals generated by GNSS satellites and viewed through Earth’s limb. Parameters describing the refraction can be used to infer familiar atmospheric variables such as temperature, pressure and water vapor. The RO technique allows for increased global coverage of temperature and water vapor through the large number of daily observations and as a result plays an important role in the enhancement of Numerical Weather Prediction and other atmospheric-related studies.
