Global Positioning System (GPS) tomography analyses of water vapor, complemented by high‐resolution numerical simulations are used to investigate a Mistral/sea breeze event in the region of Marseille, France, during the ESCOMPTE experiment. This is the first time GPS tomography has been used to validate the three‐dimensional water vapor concentration from numerical simulation, and to analyze a small‐scale meteorological event. The high spatial and temporal resolution of GPS analyses provides a unique insight into the evolution of the vertical and horizontal distribution of water vapor during the Mistral/sea‐breeze transition.
