GNSS radio occultation L2B temperature, pressure, and water vapor retrieval for COSMIC1 as contributed by ROMSAF, version 2.0 (gnssro_cosmic1_romsaf_l2b)
Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/1ylz27bhsdth
This dataset provides Global Navigation Satellite System (GNSS) Radio Occultation (RO) Temperature, Pressure, and Water Vapor data from the Constellation Observing System for Meteorology Ionosphere & Climate - 1 mission as contributed by the Radio Occultation Meteorology Satellite Application Facilities.
Description
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.
