GNSS radio occultation L1B excess phase and amplitude for PLANETIQ as contributed by UCAR, V2.0 (gnssro_planetiq_ucar_l1b)

This dataset provides Global Navigation Satellite System (GNSS) Radio Occultation (RO) Excess Phase and Amplitude data from the PlanetiQ as contributed by the University Corporation for Atmospheric Research. 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.
