Rainfall measurements collected since 2003 by a network of daily reading raingauges deployed in the Hombori super site.
-
Rainfall measurements collected over a network of daily reading raingauges, installed on a square of 10 km X 10 km (6 East-West lines of 10 km each, separated by 2 km from each other) located at the center of the Diantandou kori basin. The network is installed through a catena from the bottom of Dantiandou kori valley (Banizoumbou) to the Bani Kossey depression (10 km). The network is visited each day to record previous rainfall.
-
Long term rainfall measurements collected since 1990 (Long Observation Period) by 30 recording raingauges over the Niamey meso site (1.6-3.1°E/12.8-14.1°N) with a regular sampling of about 25x25 km². NB: Negative values are missing values. Negative value other than -9999.9 is missing value estimated from the bucket. For a period with such missing data, although the same value is indicated for each timestep, the value applies to the whole time period.
-
Rainfall measurements collected since 2005 (Long Observation Period) by recording raingauges deployed along a north south transect (from 14.7 to 17° N, up to 10 gages). NB: Negative values are missing values. Negative value other than -9999.9 is missing value estimated from the bucket. For a period with such missing data, although the same value is indicated for each timestep, the value applies to the whole time period.
-
Rainfall measurements collected since 1999 by recording raingauges to complement and densify the Oueme (CL.Rain_O) network, in particular over the Donga basin. NB: Negative values are missing values. Negative value other than -9999.9 is missing value estimated from the bucket. For a period with such missing data, although the same value is indicated for each timestep, the value applies to the whole time period.
-
Rainfall measurements collected since 2005 (Long Observation Period) by recording raingauges deployed in the densified area : 1.2-1.9°W/15-15.7°N, up to 18 gages. NB: Negative values are missing values. Negative value other than -9999.9 is missing value estimated from the bucket. For a period with such missing data, although the same value is indicated for each timestep, the value applies to the whole time period.
-
Rainfall measurements collected since 1999 (Long Observation Period) by recording raingauges over the Oueme basin (1.4-2.9°E; 8.9-10.2°N). It was designed for a homogeneous coverage of the basin with 29 gages. NB: Negative values are missing values. Negative value other than -9999.9 is missing value estimated from the bucket. For a period with such missing data, although the same value is indicated for each timestep, the value applies to the whole time period.
-
Rainfall measurements collected since 1999 by 5 recording raingauges deployed over the East Niger (Tillaberi, Konni, Tahoua, Maradi, Zinder). NB: Negative values are missing values. Negative value other than -9999.9 is missing value estimated from the bucket. For a period with such missing data, although the same value is indicated for each timestep, the value applies to the whole time period.
-
Rainfall measurements collected since 2005 (Enhanced Observation Period of the AMMA project) by ~25 recording raingauges to complement and densify the meso site network (CL.Rain_N), in particular over the Niger Central supersite. NB: Negative values are missing values. Negative value other than -9999.9 is missing value estimated from the bucket. For a period with such missing data, although the same value is indicated for each timestep, the value applies to the whole time period.
-
Monitoring rainfall at the DMN station in Cotonou for climatological reference. NB: Negative values are missing values. Negative value other than -9999.9 is missing value estimated from the bucket. For a period with such missing data, although the same value is indicated for each timestep, the value applies to the whole time period.
