Description:

This is an updating archive of radio occultation data using the transmitters of the Global Navigation Satellite Systems (GNSS) as generated and processed at the COSMIC DAAC, the Jet Propulsion Laboratory of Caltech, and the Radio Occultation Meteorology Satellite Application Facility (ROM SAF).

This dataset is funded by the NASA Earth Science Data Systems and the Advancing Collaborative Connections for Earth System Science (ACCESS) 2019 program.

This is an updating archive of radio occultation data using the transmitters of the Global Navigation Satellite Systems (GNSS) as generated and processed at the COSMIC DAAC, the Jet Propulsion Laboratory of Caltech, and the Radio Occultation Meteorology Satellite Application Facility (ROM SAF).

This dataset is funded by the NASA Earth Science Data Systems and the Advancing Collaborative Connections for Earth System Science (ACCESS) 2019 program.

Update Frequency:

The dataset is updated monthly for JPL and CDAAC contributions only.

Resources:

1. resource:
   • Description: Three types of data exist in a directory hierarchy that includes the contributing processing center, the radio occultation mission, the file type, and the date: (1) Calibrated excess phase (calibratedPhase), a type of level 1b data product; (2) retrievals of bending angle, refractivity, dry temperature and dry pressure (refractivityRetrieval) as functions of geopotential height, a type of level 2a data product; and (3) atmospheric retrievals of pressure, temperature, and water vapor as functions of geopotential height (atmosphericRetrieval), a type of level 2b data product. In addition, a suite of JSON files containing the records that constitute of database of the contents of the archive. A utility to build a DynamoDB database based on these records can be found in the Github utilities.
