The Hydrologic Atmospheric Pilot EXperiment in the Sahel (HAPEX-Sahel) was carried out in Niger, West Africa, during 1991 - 1992, with an intensive observation period (IOP) in August - October 1992. It aims at improving the parameterization of land s

Publikováno v: Water Resources Research. 33:2563-2569

Regional scale fluxes of sensible heat, latent heat, and CO2 are estimated by means of a method which involves the heat and mass budget of the convective boundary layer (CBL). This method is based upon an integrated form of the conservation equation

The HAPEX-Sahel experiment was organized to investigate the impact of water, energy and CO2 fluxes at the soil-vegetation-atmosphere interface on climate processes in the Sahelian region. Measurements of the energy balance components, CO2 flux and so

The variability between surface flux measurements at the fallow sites of the three HAPEX-Sahel supersites is examined over periods of three or four consecutive days. A roving eddy correlation instrument provided a common base for comparison at each s

Accurate partitioning of the available energy at the surface into sensible and latent heat flux is crucial to the understanding of the interactions between the hydrological cycle and climate processes at regional and global scale. This is however a c
