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. This paper provides an overview of work performed to monitor soil moisture, and to model the flux of water and vapor over the FIFE site. Investigations ranged from ground based work which made surface moisture measurements by impedance probes, to modeling work which collected rainfall data on a spatially distributed scale. Airborne monitors mounted on aircraft studied the site from different elevations, making use of microwave based techniques which have been developed over recent years. A gamma-ray based system was also deployed. Unfortunately the instrument which would have provided the area wide survey capability was not ready in 1987, and overcommitted in 1989, and provided little input to this program.
