Abstract

A discussion of a series of airborne measurements of atmospheric optical properties in Europe. Visible spectrum measurements made using an instrumented C-130 aircraft between 0.5 and approximately 6 km above ground level are described with respect to experimental procedures, results and application of the data to the determination of atmospheric contrast transmission. Data locations are illustrated as are the primary radiometer systems utilized to make the measurements. Sample data from flights conducted during 1976 and 1977 are presented illustrating irradiance levels beneath scattered to broken cloud decks, and total volume scattering coefficient variations as a function of altitude above ground level. Comparisons between scattering coefficient and relative humidity profiles are illustrated and the data base availability is reviewed.
