Abstract : The paper describes a system for recording surface radiative temperatures by remote sensing with a PRT5 by attaching the instrument to the steps of a light aircraft. Calibration before and after flight and tests for atmospheric attenuation showed observations to be accurate to within a few tenths of a degree C. For maximum efficiency short flights between clearly identifiable check points are desirable. Data were recorded on 1/4-inch magnetic tape, which gave high precision but produced analysis difficulties. (Author)
