The Intensive Observing Period of the Hapex-sahel (Hydrologic and Atmospheric Pilot Experiment in the Sahel) international experiment was held in Niger in 1992.
Objectives
Evaporation and water/energy balance studies in a dry tropical region ,in relation with the characteristics of the soils ,the vegetation cover and the atmosphere ,with:
- The measurement of the water and energy fluxes.
- The spatial integration of data.
Data
- Ground measurement :water ,gaz and energy fluxes ,rainfall ,meteorology ,runoff ,soil moisture ,groundwater level ,vegetation measurements ,etc.
- Airborne measurements : fluxes and remote sensing data.
- satellites : SPOT, NOAA/AVHRR, Landsat TM, ERS-1, METEOSAT.
- bibliographic data.
Distribution
- Web Server and CD-ROM (restriced to the PI until 1997).
- Data base developed by LERTS, IRD and CNES.
