THERMAL INFRARED FOR SOIL TEMPERATURE STUDIES

SEASONAL REMOTE SENSING FLIGHTS BY NASA AND THE UNIVERSITY OF MICHIGAN WERE MADE OVER AN AREA OF ALLUVIAL SOILS. DETAILED SOIL SURVEYS WERE RELATED TO THERMAL INFRARED IMAGERY IN A MANNER WHICH SHOWS THAT SURFACE SOIL TEMPERATURES CAN BE INDICATIVE OF SUBSURFACE SOIL CONDITIONS. THE WARMING AND COOLING OF SOIL DEPENDS ON MANY FACTORS. THE SPECIFIC SOIL CHARACTERISTICS THAT MOST INFLUENCE HEAT TRANSFER AND STORAGE ARE WATER CONTENT, SIZE OF SOIL PARTICLES AND PORE SPACE. THE TIME OF DIURNAL AND THE SEASON CAN BE IMPORTANT FACTORS IN CONDUCTING REMOTE SENSING MISSIONS. THERMAL INFRARED SENSING GIVES A QUALITATIVE INDICATION OF SOIL WATER IN APPROXIMATELY THE TOP 50 CM. OF BARE SOIL. THE MAGNITUDE OF DIURNAL TEMPERATURE OSCILLATIONS CAN ALSO BE AN INDICATOR OF SOIL MOISTURE CONTENT. THUS THERMAL IMAGERY CAN BE VALUABLE FOR MANAGEMENT OF FARM RESOURCES. THE INVESTIGATION DESCRIBED IS INTENDED AS INITIAL EVIDENCE THAT SOIL CHARACTERISTICS INFLUENCE THE THERMAL REGIME OF SOILS IN A MANNER THAT CAN BE HELPFUL TO THE SOIL SURVEYOR. /AUTHOR/
