Abstract : The report compares cloud-cover observations made by ground observers and relative cloud-cover estimates determined from satellite-measured brightness values. Comparisons are made when each type of cloud (9 low type, 9 middle type, and 9 high type) are found alone and also with various combinations of other clouds. Over 66,000 incidences are compared for observations taken over the China mainland and portions of Southeast Asia. Satellite observations from the ESSA and ITOS series of satellites are used. Both tabulated and graphical presentations of the results are included along with the author's comments on the investigative procedures and findings. (Author)
