Abstract
A method for processing remotely acquired imagery data includes identifying a region of lowest intensity in each of a plurality of different images for a plurality of different spectral bands and estimating first values for upwelling path radiance for each of the different images according to an intensity in the region in each of the different images. The method further includes selecting a visibility value and calculating second values for the upwelling path radiance for each of the different images, each of the second values based on a radiation transfer model, the radiation model generated using the visibility value and the meta-data. The method can also include comparing the first and the second values for the upwelling path radiance for the different images, adjusting the visibility value based on the comparison, and repeating the calculating, the comparing, and the adjusting steps until a termination condition is met.
