This dissertation describes the design, development, chemistry and results of flow actinometers used to measure atmospheric photolysis rates directly, and electronic UV photometers designed or modified to give a response directly related to photolysis rates. These photometers measured albedos of many surfaces at altitudes from 0-6 km. While natural surfaces such as vegetation and oceans have a UV albedo near zero, dense clouds and snow have an albedo near one. With increasing altitude, molecular and particulate scattering often increase the effective albedo with respect to photolysis rates. The effective albedo over the ocean is 7% at 0.05 km and 25 to 45% at 5.0 km for varying amounts of haze.
