Webin surface irradiance of about 7% for a surface albedo changing between 0.16 and 0.24. Wang and Lenoble ( 1994 ) found that a change in albedo from 0.03 to 0.1 increased irradiance by 2.1% over the 290-300-nm range for a solar zenith angle of 20° and 350-DU total column ozone. Both these results agree well with the results found in this study. d.
