Temperature measurement of the land-surface. Measuring methods and their application for the survey of subsoil water

Technical Report:

Abstract

The variation of the water content of a landscape has been investigated. The method of measurement was the use of the radiation of heat from the land surface. The radiation was measured by an airborne infrared scanner and a manual infrared thermometer. The water content and the temperature of the soil were recorded separately. The principle of the measurement is the slow reaction of a soil with a high water content to the temperature changes between day and night. Comparison of different methods points to an association of temperatures and water content. The correlation of the results is very low so that a mapping of water content in the area of Vibydalen becomes uncertain. The experiment displays the requirements of the accuracy in measuring methods.
