High-Resolution Atmospheric Water Vapor Fields by Spaceborne Geodetic Sensing, Tomographic Fusion, and Atmospheric Modeling

The AtmoWater project, High-Resolution Atmospheric Water Vapor Fields by Spaceborne Geodetic Sensing, Tomographic Fusion, and Atmospheric Modeling is an international collaboration consisting of four institutes of Karlsruhe Institute of Technology (KIT) and ETH Zurich. The project is coordinated by the Geodetic Institute of KIT and funded by German Research Foundation (DFG, project number: 321886779) and Swiss National Science Foundation (SNSF) for the duration of three years (2018-2021). As a vital component of the hydrological cycle, water vapor represents a main driver for the generation and spatio-temporal distribution of clouds and precipitation. By using GNSS and InSAR based techniques in combination with high resolution regional atmospheric weather models and geostatistical data merging techniques, the proposed project aims at developing and evaluating new approaches to derive improved spatio-temporal estimates of the atmospheric water vapor distribution.
