The Trans-African Hydro-Meteorological Observatory (TAHMO) aims to develop a vast network of weather stations across Africa. Current and historic weather data is important for agricultural, climate monitoring, and many hydro-meteorological applications.

The TAHMO initiative is committed to serving the public by advancing the free and open exchange of hydro-meteorological data collected with its monitoring stations. By allowing the free download of all raw TAHMO data for scientific research and governmental applications, TAHMO supports World Meteorological Organization (WMO) Resolution 40 and Resolution 25. Commercial applications of TAHMO data are considered on a case-by-case basis.
