Description du jeu de données
RésuméDocumentation of rainfall in sahelian and saharo-sahelian zones. The aim is to characterize the spatial and temporal variability of rainfall within a densified zone of approximately 0°7 by 0°7 degrees within the Gourma meso-scale site. Data will be used in modelling and assimilation activities, as well as for validation of satellite products.

Elaborated product(s): Rainfall maps on a regular grid (0°5x0°5 / 6 hours) over the domain in free access. For higher resolution products, contact PI.
Strategie d'observationDirect measurements of rainfall thanks to tipping buckets gages. The interception surface for each gage is 400 cm2 , each tip is equivalent to an amount of 0.5 mm of rain.

A network of tipping bucket gauges, spread over the Hombori ‘square’ (0°7x0°7 approximately Rainfall measurements collected since 2005 by recording raingauges deployed in the densified area 1.2-1.9°W / 15-15.7°N, up to 20 gauges.

Information sur l'utilisation des données
Conditions d'utilisation des donnéesPermission is granted to use these data in research and publications when accompanied by the following statement: "The AMMA-CATCH regional observing system was set up thanks to an incentive funding of the French Ministry of Research that allowed pooling together various pre-existing small scale observing setups. The continuity and long term perenity of the measurements are made possible by an undisrupted IRD funding since 1990 and by a continuous CNRS-INSU funding since 2005."
