GPS and Surface Obs. Array for Monitoring PW and Precipitation

This project aims to understand the relationship between PW (column water vapor) and precipitation, improve knowledge and model representations of moisture and precipitation, and monitor intra- and inter-annual variations. It involves combining existing GPS instrumentation with new sets in Northwestern Mexico and using GPS processing for near real-time access and monitoring.
