Abstract : A balloon flight was made July 8, 1966, with a downward looking spectral radiometer which measured the absolute spectral radiance of earth in the region from 8.5 to 16.0 microns as viewed from the balloon altitude. During the course of the flight the balloon traversed a number of different types of terrain. The observed spectral radiances show significant differences. Some of the differences appear to be due to changes in surface temperatures. There are a number of cases when the differences are definitely spectral in character and cannot be explained on the basis of temperature changes alone. It has not been possible however to associate the differences with any apparent geological parameter. (Author)
