Abstract : Only rare measurements are so far available of cloud albedo under varying cloud conditions. Data of such type, however, are urgently wanted for a better estimate of observations by spaceborne operators and sensors. An instrumented cable car overcomes a height difference of approx. 2 km. The cable car is frequently under, in, or above clouds of most varied horizontal and vertical extension and different structure in the upper and lower sections. Therefore in a horizontal plane of incidence the visible part of radiation incoming from above and below was recorded by pyranometers during the cable car runs. These runs were executed under cloud conditions being such that applicable results are to be expected in terms of the topic. Data are presented in graphs, giving finally the value of cloud albedo as a function of altitude and cloud type. (Author)
