To estimate sensible heat flux using thermal infra-red temperature T/sub r/ over sparse semi-arid vegetation, a knowledge of either the corrective term kB/sup -1/ or the difference between radiometric and aerodynamic surface temperatures T/sub r/-T/sub o/ is usually required. Several experimental data sets acquired over various sparse vegetation in semi-arid areas (fallow savannah and millet field of HAPEX-Sahel, grassland and shrubland of MONSOON' 90) are used to study the experimental behavior of these variables. When considering the extreme variability of kB/sup -1/ and the difficulty in predicting its value, the relationship between T/sub r/ and T/sub o/ was more thoroughly studied and parameterized using the conceptual two-layer model of Shuttleworth and Wallace (1985)
