Water vapor column abundance retrievals during FIFE
- California Inst. of Technology, Pasadena (United States)
This work is part of the First International Satellite Land Surface Climatology Project (ISLSCP) Field Experiment (FIFE), an international land-surface-atmosphere experiment aimed at improving the way climate models represent energy, water, heat, and carbon exchanges, and improving the utilization of satellite based remote sensing to monitor such parameters. The authors report on the use of a sunphotometer to extract column water vapor data over FIFE. By using appropriate filters the sunphotometer can collect data on water vapor and ozone. Here the authors report on instrumentation, applications, and results from the field campaigns over FIFE for this instrumentation. Two such instruments were deployed. The traditional instrument for water column measurements is the radiosonde, but it is known to have problems also. These measurements provide only point values. Airborne imagery suggests there is a greater than 10% spatial variability over the FIFE site, associated with vegetation and surface topography.
