Daily and daytime meteorological data measured by the AMMA-CATCH observatory at Belefoungou (BE, Benin, Nalohou (NA, Benin). Gaps were filled using linear regression obtained from the record of the nearest AMMA-CATCH sensor. In the absence of a nearby record (e.g. at DA), gaps were filled by linear or spline interpolation over time on a moving average of the variable to be filled, to restore temporal dynamics.
