Initial results from a radiative transfer model investigation are given, followed by empirical coefficients which were deduced through multivariant regression analysis of Nimbus-7/ERB broadband data and/NOAA-7/AVHRR narrowband data. Planetary scenes were grouped into five major categories. Strong variations in the two channel AVHRR narrowband albedo observations were noted for different scene classifications which emphasize the potential error in using a single AVHRR channel 1 (0.58-0.68 micrometer) albedo determination as has historically been done. The results presented should allow improved albedo calculations when one is limited to AVHRR narrowband data. 收起
