This symposium will review (1) the latest methods and results for atmospheric sensing using ground-based GPS networks in the USA, Europe, Japan and elsewhere; (2) space-based (occultation) methods including new retrieval algorithms and strategies to enable routine retrieval of water vapor data from the lower troposphere; (3) use of ground and space-based GPS data for two and three dimensional modeling of the upper and lower atmosphere; and (4) future GPS occultation satellites. Rapidly growing networks of ground-based continuous GPS receivers, and new constellations of GPS occultation satellites represent a major new data source for weather and space weather analysis and prediction, and monitoring of climate and climate change. We especially encourage contributions related to the impact of these new techniques in the areas of weather and space weather analysis and prediction, climatology and the calibration of conventional meteorological satellite measurements.
