An atmospheric water vapor sensing system using Global Positioning Satellites (GPS) to determine the refractivity and Slant-path Water Vapor (SWV) between an Earth-based GPS receiver and a plurality of satellite-based GPS transmitters. Either the refractivity measure or the SWV measure can be input directly into weather forecasting models. SWV is the integrated atmospheric water vapor in a column of atmosphere at an acute angular line-of-sight path between the Earth-based GPS receiver and any one of the plurality of satellite-based GPS transmitters. SWV sensing facilitates atmospheric soundings over land and water to provide global scale high resolution atmospheric tomography for use in operational meteorology and meteorological forecasting.

An atmospheric water vapor sensing system for use in forecasting atmospheric conditions in Earth\s atmosphere, said system comprising: at least one Earth-based receiver, at least one satellite-based transmitter, and a signal on a slant-path therebetween; and means for determining a refractivity measurement of said signal based on an excess path delay of said signal induced by weather related atmospheric constituents along said slant-path.
