Abstract:
Adequate information on spatial and temporal distribution of surface energy balance components
in the sub-Sahara region of West-Africa are critical for sustainable management of water
resources besides better understanding of water and heat exchange processes between land
surface and atmosphere. this study aim to; estimate surface energy fluxes and evapotranspiration
in the Sudanian savannah in West Africa using both Eddy Covariance EC and remote sensing
technique, and compare the result from the two techniques. Three EC stations' data installed
close to the Ghana-Burkina-Faso border in West Africa were used to determine the surface
energy fluxes. SEBAL (Surface Energy Balance Algorithm for Land) model was used to
estimate the regional distribution of the surface energy fluxes and evapotranspiration from these
sites. When comparison was made between the SEBAL modelled result with data from the EC
stations, findings showed relatively good correlation of more than 0.6 from the three stations
respectively. |
