Measuring water vapor in the atmosphere is crucial for understanding the greenhouse effect and the hydrological cycle. Satellites, both geostationary and orbiting, offer the possibility of creating valuable historical data series to improve both short-term weather forecasts and climate projections. This paper presents a method for making the best use of this data. With specific technical solutions, it demonstrates that it is possible to analyze global water vapor concentrations from 1995 to the present day, with the possibility of extending the measurements to 2040.
