-
Sensible & latent heat, CO2 fluxes over a specific land cover type (Faidherbia albida agro-silvo-pastoral parkland).
-
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.
-
Automatic measurements of water levels in creeks converted into flow.
-
Rainfall measurements collected between 1990-2004 (EPSAT project) by up to ~100 recording raingauges to complement and densify the meso site network (CL.Rain_N). 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.
-
Aboveground herbaceous mass, vegetation cover fraction, LAI are monitored in sites located within the Hombori super-site and representatives of the 3 main components of the landscape: sand dunes (Agoufou, Hombori Hondo, Tara and Timbadior), erosion surface (Eguerit), seasonally inundated clay soils (Kelma plain) and millet (Bilantao). For mass estimation, the herbaceous layer is monitored using a stratified random technique. Measurements are performed at least every month during the rainy season, from June to mid-October and twice during the dry season. LAI is estimated using hemispherical photographs. For the Kelma forest, hemispherical photographs are also used to derive the Plant Area Index (PAI).
-
Soil moisture and temperature profiles (0- ~5m) in various types of soil/vegetation.
-
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 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.
-
Observation of the seasonal cover dynamics and funtionning. States of each phenophase were recorded using the following classification: 0 = absent, 1 = beginning, buds for leaves and flowers and early stage of maturity for fruits, 2 = weak, 10-50% of the shrub covered with mature or ripe organs, 3 = peak, over 50% of the shrub covered with mature or ripe organs, 4 = declining, 10-50% of the shrub covered with senescent organs (dissemination beginning for fruits), 5 = end, over 50% of the shrub covered with senescent, dry and falling organs.
-
Flood event measured in 4 (Tondikiboro) and 2 (Mele Haoussa) embeded catchments. Sediment loads are sampled during selected rainfall events in Tondikiboro.
