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, and has been continuously operating until 2019.

The DJ station was the unique permanent station maintained in equatorial Africa within IGETS. The superconducting gravimeter was 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 1-minute raw gravity and pressure record (Level-1),
the 1-minute corrected gravity and pressure, ready for tidal analysis (Level-2) produced by EOST,
the 1-minute gravity residuals (Level-3) produced by EOST.

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