S6A_RO_1B_NRT_NC__: Sentinel-6 Near-Real-Time Atmospheric Bending Angle Profiles

NASA's Jet Propulsion Laboratory generates Level 1B bending angle retrievals from the Sentinel-6A Michael Freilich satellite using Global Navigation Satellite System Radio-Occultation. Each data granule represents a single occultation event, providing a high-resolution vertical profile referenced to a specific geodetic location. This near-real-time dataset supports monitoring of temperature and humidity changes in the troposphere and stratosphere.

Use Cases

• Assessing tropospheric and stratospheric temperature changes based on GNSS RO sounding technique.
• Supporting numerical weather prediction models with near-real-time vertical atmospheric profiles.
• Validating climate models using high-resolution bending angle data from a collaborative international mission.
• Tracking humidity changes in the atmosphere based on radio-occultation retrieval variables.

Strengths

• Data is generated by NASA's Jet Propulsion Laboratory, a leading institution in space science.
• Provides near-real-time (NRT) retrievals, indicating operational utility for time-sensitive applications.
• Derived from the Sentinel-6A satellite, a collaborative mission involving NASA, EUMETSAT, ESA, NOAA, and CNES.

Limitations

• Column names and dataset size (rows, file size) are not provided in any source, limiting technical assessment.
• One platform lists a specific 'other-license-specified', while another lists 'None', creating a license conflict.
• Metadata completeness is low; critical details like data volume and specific column structure are unknown.
