Where can I find water vapor images?

Click For Summary
SUMMARY

This discussion focuses on the search for daytime sky images captured within specific water vapor absorption bands at 940nm, 1600nm, 1860nm, 2700nm, and 2900nm. The user aims to analyze multispectral images to identify slight water vapor differences of approximately 1% over distances of 500 to 1500 meters. They express difficulty in finding published results and highlight the high cost of bandpass filters for wavelengths above 1000nm. Resources such as NOAA and the European Space Agency are suggested for potential image sources.

PREREQUISITES
  • Understanding of water vapor absorption bands and their significance in atmospheric studies.
  • Familiarity with multispectral imaging techniques and image processing methods.
  • Knowledge of bandpass filters and their application in capturing specific wavelengths.
  • Basic skills in searching scientific databases and archives for remote sensing imagery.
NEXT STEPS
  • Research "NOAA GOES satellite water vapor images archive" for relevant datasets.
  • Explore "European Space Agency remote sensing imagery" for additional resources.
  • Investigate "image processing techniques for multispectral data" to enhance water vapor detection.
  • Look into "affordable bandpass filters for atmospheric imaging" to reduce equipment costs.
USEFUL FOR

Atmospheric scientists, remote sensing researchers, and hobbyists interested in analyzing water vapor differences in the atmosphere using multispectral imaging techniques.

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.
