Equipment is described that has been developed to investigate the propagation of infra-red radiation through ground layers of the atmosphere over various broad-band wavelength regions from 1 to 12 micrometers for pathlengths up to 10 km. Propagation studies undertaken to date have included absolute transmission and relative transmission measurements in a terrain environment, and terrestrial scintillation observations. The various errors associated with transmission measurements are discussed. (Author).
