GNSS radio occultation L2A bending angle, refractivity, and dry pressure for GRACE as contributed by JPL, version 2.0 (gnssro_grace_jpl_l2a)

This dataset provides Global Navigation Satellite System (GNSS) Radio Occultation (RO) Bending Angle, Refractivity, and Dry Pressure data from the GRACE (Gravity Recovery and Climate Experiment) mission as contributed by the Jet Propulsion Laboratory. 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.
