Abstract : The results of an examination of a TIROS III five-channel radiometer, with special reference to the establishment of calibration procedures, and to the evaluation, relatively and absolutely, of data assembled in specific spectral regions. The principal subjects discussed are: (1) calibration techniques utilizing mono chromators to determine the relative spectral response of the various channels. (2) the selection of optimum sources for employment in these calibrations. (3) the use of blackbody radiators to establish the integral wavelength sensitivity of the radiometer in the infrared region and also by the use of the longwavelength cut-off characteristics of selected filters to assess the wavelength response of the radiometer in broad spectral bands to provide a check on results collected by the monochromator method; and (4) the use of an integrating hemisphere to establish the integral wavelength sensitivity of the radiometer in the visible and near infra-red regions.
