141 Remote Sensing at Multiple Scales: The Bushland Evapotranspiration and Agricultural Remote Sensing Experiment, 2008

Oral Session
A03 Agroclimatology & Agronomic Modeling
This session will present research results from a major field remote sensing campaign held at Bushland, Texas. The measurements included eddy covariance and Bowen ratio flux large weighing lysimeters, a sub-experiment involving E and T separation with sap flow gages and microlysimeters, multiple heat flux measurements to look at row-interrow placement effects and to compare heat flux measurement methods, a sub-experiment on thermal infrared on the row-interrow scale with above-row, under-row measurements. Aircraft were used for thermal infrared imaging and another for flux measurements, and satellite data.
