Exploration Basis
Analyze if coupling remote sensing and field data is effective for determining geothermal areas
Thermal infrared (TIR) data from the spaceborne ASTER instrument was used to detect surface temperature anomalies in the Coso geothermal field in eastern California. The identification of such anomalies in a known geothermal area serves as an incentive to apply similar markers and techniques to areas of unknown geothermal potential. Field measurements were carried out concurrently with the collection of ASTER images. The field data included reflectance, subsurface and surface temperatures, and radiosonde atmospheric profiles. Techniques were applied that specifically target to correct for thermal artifacts caused by topography, albedo, and thermal inertia. This approach has the potential to reduce data noise and to reveal thermal anomalies which are not distinguishable in the uncorrected imagery. The combination of remote sensing and field data can be used to evaluate the performance of TIR remote sensing as a cost-effective geothermal exploration tool.
