A water cloud was produced in our laboratory cloud chamber, and the infrared optical depth shown in Fig. 1 was measured with a Fourier Transform Infrared Spectrometer (FTIR). We cooked-up an algorithm (rather than looked-up) that inverts the Fredholm Integral Equation to obtain particle size spectra from the measurement as shown in the second figure. The final figure is a measured water vapor spectrum at a course resolution of 32 inverse cm that is used to obtain the water vapor concentration.
