Abstract

A global positioning system (GPS) tomography is used to retrieve a three-dimensional water vapor distribution from the slant integrals. To determine the physical solution, simple constraints are applied to the GPS tomography process: no negative water vapor, and exponential decay of water vapor with height at high altitude. Applying the constrained GPS tomography to an International H₂O Project (IHOP) GPS dataset, the retrieved water vapor distribution of a storm on 12-13 June 2002 matches the GEOS water vapor images and sounding from the IHOP central facility. Results indicate that an accurate, real-time GPS tomography analysis can be used as a direct and independent verification of water vapor distribution.
