- 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. RO data can be queried, subsetted and downloaded using the Python API [awsgnssroutils](https://pypi.org/project/awsgnssroutils/).
