Resumen
Global Positioning System (GPS) radio occultation (RO) from low Earth-orbiting satellites has increased the quantity of high-vertical resolution atmospheric profiles, especially over oceans, and has significantly improved global weather forecasting. A new system, the Global Navigation Satellite Systems Instrument System for Multistatic and Occultation Sensing (GISMOS), has been developed for RO sounding from aircraft. GISMOS also provides high-vertical resolution profiles that are insensitive to clouds and precipitation, and in addition, provides greater control on the sampling location, useful for targeted regional studies. The feasibility of the system is demonstrated with a flight carried out during development of an Atlantic tropical storm. The data have been evaluated through a comparison with dropsonde data. The new airborne RO system will effectively increase by more than 50% the number of profiles available for studying the evolution of tropical storms during this campaign and could potentially be deployed on commercial aircraft in the future.Key Points<list list-type=bulleted id=grl51421-list-0001> <list-item id=grl51421-li-0001>First time airborne radio occultation shown to agree with independent data <list-item id=grl51421-li-0002>First time airborne RO measurements have been collected in a tropical storm <list-item id=grl51421-li-0003>It demonstrates the potential for an operational system on commercial aircraft NSF Ross Fellowship Schlumberger Faculty for the Future Fellowship Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) NASA Earth System Science Research Fellowship Univ Calif San Diego, Scripps Inst Oceanog, La Jolla, CA 92093 USA Purdue Univ, Dept Earth Atmospher & Planetary Sci, W Lafayette, IN 47907 USA Univ Estadual Paulista, Fac Ciencias & Tecnol, Presidente Prudente, Brazil Univ Colorado, Dept Aerosp Engn Sci, Boulder, CO 80309 USA Purdue Univ, Dept Aeronaut & Astronaut Engn, W Lafayette, IN 47907 USA Univ Estadual Paulista, Fac Ciencias & Tecnol, Presidente Prudente, Brazil NSFS05-39696 NSFSGER-0802887 NSFAGS 1015904 CAPES: 1834/07-0 NASA Earth System Science Research FellowshipNNX11AL50H
