| Description du jeu de données | |||
| Résumé | Documentation of rainfall variability on the Niamey mesoscale site. One aim is to provide rainfall inputs for computing the water balance at the rain event and larger times; a second aim is to characterize the statistical properties of the rainfields and to study their scaling properties. | ||
| Strategie d'observation | Regular spatial distribution of the 30 gauges in order to cover the 17600 km² Area with a regular sampling of about 25x25 km²; this strategy results from previous studies, using a denser network of a hundred gauges on this site. These studies showed that a sampling resolution of about 30 km ensure a good documentation of the rainfall variability at the time scale of the rain event. | ||

| Information sur l'utilisation des données | |||
| Conditions d'utilisation des données | Permission 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." | ||
