A study of the sensitivity of land surface parameterizations to the inclusion of different fractional covers and soil textures
- Novi Sad Univ. (Yugoslavia) Agricultural Univ., Wageningen (Netherlands)
The effect of a wide range of soil textures, from sand to clay, on atmospheric fluxes from a single type of plant (maize) cover was examined for four different fractional covers to determine the sensitivity of land surface parametrization to the inclusion of fractional plant covers and soil textures. The results of the analysis support the well-known fact that surface fluxes are strongly dependent on soil texture. Finer classifications of soil textures from sand to clay indicate that there exist two regimes of latent heat flux variability, where the latent heat flux is (1) independent of the fractional cover, leaf-area indices of the surface, and soil texture (from loamy sand to silt loam), and (2) dependent on the fractional cover and leaf-area indices but independent of the soil texture (from loam to silty clay). 20 refs.
