Night Crew Labs, LLC author Goel, Ashish author Kosh, Jonathan author Reid, Tyler G. R. author Snyder, Corey R. author Tarantino, Paul M. author tableDigital The global Navigation Satellite System (GNSS) radio occultation (RO) technique has proven to be an effective tool for Earth atmosphere profiling. Traditional spaceborne RO satellite constellations are expensive with relatively low sampling rates for individual satellites. Airborne RO platforms can provide much higher spatial and temporal sampling of ROs around regional weather events. This dataset is the result of a paper which explores the capability of a low-cost and scalable Commercial-Off-The-Shelf (COTS) GNSS receiver onboard high-altitude balloons. The atmospheric refractivity profile retrievals from balloon-borne RO payloads obtained from two flight campaigns (World View and ZPM-1) are archived. This dataset is available to the public for a wide variety of uses including scientific research and analysis.
