The FIFE Follow-On project was a large-scale climatology project conducted on the Konza Prairie in Kansas from 1990 through 1993. It includes additional analysis of the data collected in the First ISLSCP (International Satellite Land Surface Climatology Project) Field Experiment (FIFE) from 1987 through 1989, as well as additional field measurements.

The over-arching goal of the FIFE Follow-On project was to develop a physically based approach for using satellite remote-sensing systems. More specifically the project focused on:

• understanding the biophysical processes controlling the fluxes of exchanges of radiation, moisture, and carbon dioxide between the land surface and the atmosphere
• developing and testing remote-sensing methodologies for observing these processes at a pixel level
• understanding how to scale the pixel-level information to regional scales commensurate with modeling of global processes

The FIFE Follow-On investigators performed an extensive analysis of the remote-sensing data and modeled the original 1987-1989 FIFE data. Their studies included data from a portable automatic meteorological station (AMS), site-averaged flux data collected by many investigators, site-averaged gravimetric soil moisture data, and site-averaged neutron probe soil moisture data. The raw data were extensively cleaned and edited before the site averages were generated. The remote-sensing data were used to determine surface energy budgets, soil moisture and vegetation parameters, surface-atmosphere fluxes, and atmosphere properties. Surface-atmosphere exchanges and atmospheric boundary layer models were examined to more completely understand the dynamics measured.
