AB: Small-scale spatial variations in clear air water vapor are an important feature of the local structure of the lower atmosphere. The Multispectral Atmospheric Mapping Sensor (MAMS) flown on the NASA ER-2 aircraft collected data on small-scale spatial structure in clear air water vapor in the 6.2 - 6.9 micron water vapor band. The Aquameter Water Band Radiometer flown on the AFRL FISTA (Flying Infrared Signatures Technology Aircraft) collected spatial structure data on in three water band channels (5.4 - 7.2, 5.6 - 6.1, and 5.7 - 6.7 microns). Wave structures with spatial scales varying from tenths to tens of kilometers were observed. In addition, spatial structure in column densities of clear air water vapor have been determined from the atmospheric correction of high spatial resolution data collected by aircraft-borne hyperspectral sensors. This paper will review these measurements, discuss models for sources of the observed structure, and assess planned air and space-based data collections on small-scale spatial structure in clear air water vapor.
