Impact of Aerodynamic Resistance Formulations used in Two-Source Modeling of Energy Exchange from the Soil and Vegetation Using Land Surface Temperature Academic Article uri icon

abstract

  • Abstract Application of the Two-Source Energy Balance (TSEB) Model using land surface temperature (LST) requires aerodynamic resistance parameterizations for the flux exchange above the canopy layer, within the canopy air space and at the soil/substrate surface. There are a number of aerodynamic resistance formulations that can be used, based on K-theory or Lagrangian approaches while others are semi-empirical derived from experimental data. These formulations require a within-canopy wind profile model as well as a parameterization for heat transfer from soil surface. The effect of the various parameterization schemes on TSEB output using tower and airborne LST observations over both highly-structured perennial crops, such as orchards and vineyards, and strongly clumped natural vegetation, such as woody savanna and desert shrublands will be presented. The utility of the …
