Abstract: This paper deals with the influence exerted by natural surfaces with non-black body characteristics on surface temperature measurements using the radiation method. The difference between the true surface temperature and ...

Abstract: Past investigations by several authors have shown that in-flight calibrations should of necessity include not only the detectors but also the complete optical system of satellite scanning radiometers. Based on calibrations ...

Abstract: The accuracy of chopper-stabilized radiometers for the meteorological measurement of surface temperatures was investigated during a series of airborne trails, including tests at high altitude using a pressurized aircraft. ...

Abstract: A new type of pyrgeometer, which uses modulation of the atmospheric radiation by a mechanical chopper, has been built for the use of ground-based and airborne measurement of broadband infrared atmospheric irradiances. The ...
