A four-band, prototype, thermal-IR radiometer with a built- in radiance reference has been fabricated by CIMEL Electronique, Paris, France, for use as a field instrument. This paper briefly describes the instrument and discusses laboratory characterization measurements and results, including spectral response, linearity of better than 0.8 percent, field of view of 9.5 degrees, noise-equivalent temperature difference of 0.06-0.2 degrees C for temperatures of 0 to 75 degrees C, signal-to-noise ratio greater than 1100 for the broad band and greater than 400 for the other bands for temperatures between 10 and 80 degrees C, nonrepeatability of less than 0.35 percent after four field campaigns, and absolute calibration.
