Djougou (EOST)

The Djougou station (code DJ) in northern Benin, a Sudanian region in West Africa, was established in 2010 thanks to the financial support of INSU-CNRS France and the ANR (Agence Nationale de la Recherche) in the frame of the GHYRAF (Gravity and Hydrology in Africa) project.

The DJ station is the unique permanent station maintained in Africa belonging to the geophysical observatories funded by INSU-CNRS. The superconducting gravimeter is also contributing to the hydrological and meteorological observatory on West Africa called AMMA-CATCH (African Monsoon Multidisciplinary Analysis - Coupling the Tropical Atmosphere and the Hydrological Cycle).

You can access here different IGETS products, for the SG-060 instrument also available at the IGETS database, i.e.:

The description of the formats/products can be found in the EOST products document.
