S6A_RO_1B_POD_RNX_: Sentinel-6A Raw GNSS Radio Occultation Data

Sentinel-6A Michael Freilich, launched on November 21, 2020, provides raw Global Navigation Satellite System (GNSS) signals in RINEX-3 format for radio occultation measurements. This Level 1B product supports the generation of high-resolution vertical profiles of temperature and humidity in the troposphere and stratosphere. The data is a result of a collaborative mission between NASA JPL, EUMETSAT, ESA, NOAA, and CNES.

Use Cases

• Deriving vertical temperature profiles based on GNSS radio occultation signal bending.
• Assessing humidity changes in the troposphere using high-resolution radio occultation soundings.
• Supporting operational weather forecasting by providing raw GNSS data for assimilation into numerical models.
• Studying long-term climate indicators by analyzing stratospheric temperature trends from the radio occultation technique.

Strengths

• Data originates from the Sentinel-6A Michael Freilich satellite, a major collaborative mission involving NASA JPL, EUMETSAT, ESA, NOAA, and CNES.
• Provides raw GNSS data in the standardized RINEX-3 format, ensuring interoperability for precise orbit determination and atmospheric retrieval.

Limitations

• Critical metadata such as row count, file size, and specific column names are unavailable across all platform entries.
• The license is ambiguously listed as 'other-license-specified' without providing the specific terms.
