Summary First results of measuring UTLS water vapor in the strong water vapor bands at 1400 and 1900 nm from solar irradiance are encouraging. SSFR transmittances (absorptances) correlate well with integrated values from NOAA in situ water vapor profiles. Comparisons with atmospheric radiative transfer modeling (MODTRAN) using atmospheric profiles of water vapor, pressure, and temperature display a consistent bias in the computed transmittances as compared to measurements. This technique may provide a near real time measure of column integrated water vapor from aircraft altitude to the top of the atmosphere along the solar slant path.
