Abstract : The Federal Office for Military Technology and Procurement together with the German Military Geophysical Office (GMGO) are conducting a research effort to establish procedures to describe and to predict thermal behavior of natural backgrounds under varying meteorological conditions. The experimental phase of this effort started in 1988 with measurements of surface temperatures of different backgrounds like trees, crops, pasture, roads and buildings together with meteorological measurements. These measurements are conducted in two geographical locations, the Meppen proving ground in Northern Germany and Oberjettenberg proving ground in the Alps. The measurement campaign has a time frame of at least one year with measurements taking place during three days each month. It is anticipated to gather a data set that reflects the full range of thermal backgrounds for tactically important locations in Central Europe. One objective of this effort is to compare and evaluate thermal background models that are under development as a companion task.
