Radiometric remote sensing of mesospheric and stratospheric water vaporThe remote sensing of stratospheric and mesospheric water vapor by microwave and millimeter radiometry is described. The received radiation is emitted by and interacts with all levels of the atmosphere. The pressure dependence of the linewidth for the absorption cross section of water vapor permits retrieval of vapor mixing ratios. The 183.31-GHz line of water vapor can also be used for remote sensing of the water vapor concentration in the upper atmosphere, but due to the much stronger absorption cross section for this line, ground-based observations are difficult. To date all measurements at 183 GHz have been made from platforms above the troposphere.
