Title
Percent Cloud Cover Determination Using Electromagnetic Scattering
Abstract
A method for determining percent cloud cover using electronic imaging and physical optics of light scattering is described. This method involves taking two consecutive images using different color separation photographic filters, specifically one with a pass band in the blue region and one with a pass band in the red region. The “red” image is then divided by the “blue” image, pixel by pixel, and the percentage of pixels in the resultant image with grey levels equal to one is determined. This is the percent cloud cover. Estimates of percent cloud cover using this method were compared to visual estimates using the northern portion of 100 Central Florida skies. A strong correlation (r = 0.94) was found between the two estimates. Follow-up work on the prototype system is described. © 1989 SPIE.
