Spire GNSS Radio Occultation Data

Spire GNSS Radio Occultation Data is a commercial Level 2 atmospheric data offering distributed by Spire Global through its Weather and Climate data services.^[1] The service provides GNSS radio-occultation soundings for weather forecasting, atmospheric profile data supply, space-weather monitoring, and ionospheric data services.^[1][2] Access is commercial rather than open public download, and the offering supports atmospheric and space-weather data services rather than a self-service archive.^[1] Integration details such as delivery schema, feed format, and pricing require commercial engagement before procurement or ingestion planning.^[1] The product is relevant when an operational workflow needs externally supplied vertical atmospheric observations from an orbital GNSS-RO constellation, not image scenes or surface raster products.^[2] Evaluation should separate the measured profile use case from downstream delivery terms, because commercial access controls feed delivery and integration details.^[1]
