Abstract: A method for developing and constructing a cloud cover indicator system is described. The method involves pointing an IR radiometer vertically downward to a movable mirror and measuring the reflected sky radiation by comparing the difference in thermal radiance between clouds and the sky. To determine cloud cover it is only important to have a threshold value for the clear sky. A value for the coverage is produced by a sunning system summation of all signal lengths of one cycle.
