GNSS Radio Occultation Data on AWS Open Data

Researchers worldwide face significant barriers when attempting to access and analyze decades of high-quality atmospheric profiling data scattered across traditional data distribution systems. GNSS Radio Occultation provides highly accurate, all-weather, globally distributed profiles of temperature, moisture, and electron density — data that is crucial for earth system science.

Through NASA's ACCESS initiative, we published a comprehensive archive of processed GNSS Radio Occultation data from multiple missions (COSMIC, COSMIC-2, MetOp) onto the Amazon Web Services (AWS) Open Data program. The dataset is provided in a consistent netCDF format with comprehensive metadata and cloud-optimized storage.

Making this data freely and easily accessible accelerates earth science research, weather prediction, and space weather monitoring. It exemplifies our commitment to operational science — transitioning research capabilities to operational use for the benefit of the broader scientific and defense communities.
