Where can I find water vapor images?

    I am searching for images of the daytime sky taken within the water vapor absorption bands at 940nm, 1600 nm, 1860 nm, 2700 nm or 2900 nm. Specifically I am trying to see if multispectral images of in-band and adjacent out-of-band photos could be subtracted to show areas of slight water vapor differeneces (~1%) in a clear sky at distances of 500 meters to 1500 meters.
    I have hopes that someone must have done this and published the results, but I can't seem to find it. I would do this myself but the price of bandpass filters above 1000 nm. is very expensive.

    Thank you Tom. There is no shortage of these images taken from 22,000 miles in space. However I want to see short range, slant path (~45 degrees) images taken from the ground or horizontally from an airplane. Image processing (subtraction) may be able to enhance the water vapor difference.
