, compared to Dave's results. Planetary albedo estimated from the Coulson (1959)model Rayleigh atmosphere is shown as circles inFig. 7.Figures 8 and 9 show comparisons between thepresent model and results for the Dave Model Clatmosphere case for the spectral response functionappropriate for the visible channel on the GOESVisible and Infrared Spin Scan Radiometer (VISSR)sensor. The Dave model results for these exampleswere computed, using the Dave data set, and kindlyprovided to us by Paul Davis of

are subjectto error caused by self-induced lateral motion of theballoon (MacCready, 1965; McVehil et al., 1965; Murrow and Henry, 1965; Scoggins, 1965; Wright, 1966;Rogers and Camnitz, 1966; Armendariz and Rachele,1967). The self-induced lateral motion of the balloon iscaused by the aerodynamic forces encountered duringthe balloon's ascent through the atmosphere. Anothersource of error is the inertia of the balloon which limitsits ability to respond faithfully to sudden wind shifts.In an effort to

changes depends now uponwhat effect absorption in the aerosol layer has on theatmospheric temperature lapse rate, and how theaerosol affects infrared radiation to space. Rasool and Schneider (1971) have calculated theeffect of aerosols on scattering and absorbing visibleand infrared radiation. They conclude that the effectof aerosols in the lower atmosphere in reducing theabsorption of incoming solar radiation for the combinedsurface-aerosol system far exceeds any reduction inoutgoing infrared flux

locations and seasons may require an adjustment of thesevalues, but this is not critical for estimating Eo sincemost of its variability comes from the presence ofclouds. Secondly, we consider a Cloudy scattering atmosphere with no absorption and molecular scattering,and we assume is0tropy of the radiance reflected bythe cloud layer and the surface. Planetary and sphericalalbedos of the cloud layer are then equal, as are thecloud top and cloud base albedos. The planetary albedoA viewed by the
