Technical Abstract: Over the last several years a two-source (soil + vegetation) energy balance modeling scheme has been developed and tested using either microwave-derived soil moisture or radiometric surface temperature as the key surface boundary condition. An overview of the modeling schemes are presented. Heat flux output from both models using airborne thermal-infrared and microwave radiometers are compared and contrasted as well as comparisons with aircraft flux measurements collected during the 1997 Southern Great Plains experiment (SGP97) conducted in Oklahoma, USA. The utility of the microwave-based two-source modeling scheme in simulating surface temperatures will be assessed using the airborne radiometric surface temperature observations. The capability of providing reliable spatially distributed heat fluxes at regional scales by both modeling schemes in contrast the aircraft flux observations will be discussed.
