干旱区生态环境知识资源中心

The Engineering Research and Development Center participated in several field programs, mainly in desert areas, using ground-based and airborne thermal imagers and radiometers to investigate the thermal signatures of disturbed and undisturbed soils, including disturbed soils over buried munitions. Analysis of the thermal imagery indicates the thermal temperature difference between the disturbed and undisturbed soil varies diurnally. The thermal temperature differences have similar diurnal patterns for the different field programs and different environmental conditions. This paper presents the analysis of the field measurements and model simulations used to quantify the observed thermal temperature differences.
