## Editorial
Spire GNSS Radio Occultation Data is a commercial Level 2 atmospheric data offering distributed by Spire Global through its Weather and Climate data services.[^spire-earth-intelligence] The service provides GNSS radio-occultation soundings for weather forecasting, atmospheric profile data supply, space-weather monitoring, and ionospheric data services.[^spire-earth-intelligence][^spire-ro-explainer] Access is commercial rather than open public download, and the offering supports atmospheric and space-weather data services rather than a self-service archive.[^spire-earth-intelligence] Integration details such as delivery schema, feed format, and pricing require commercial engagement before procurement or ingestion planning.[^spire-earth-intelligence] 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.[^spire-ro-explainer] Evaluation should separate the measured profile use case from downstream delivery terms, because commercial access controls feed delivery and integration details.[^spire-earth-intelligence]
