Created in 1962 by Lamotte and Tournier (hence the name LAMTO), the Geophysical Station of Lamto is located about ten kilometers from the town of Taabo, in a reserve of 2,700 ha. It is a research center in internal geophysics (seismology) and external geophysics (climatology). The internal geophysical component relates to the study of any movement of the ground. This ranges from movements due to earthquakes to those related to underground nuclear tests. As for the external geophysical component, it concerns the study of the climate. Thus, the climatology work carried out in Lamto concerns the study of climate change and its impacts, in particular on agriculture and health, as well as the definition of strategies for reducing the greenhouse effect (warming of the atmosphere and oceans) and climate change adaptation strategies.

As part of the European Carboafrica project (2006-2009), an analyzer of atmospheric CO2 and CH4 concentrations was installed at the Lamto observatory in 2008. Monitoring of desert aerosols has also been carried out since 2015 as part of the INDAAF network.
