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 present analysis results from intercomparison flights of the three different aircraft which participated in the FIFE data collection program. These craft provided measurements of heat momentum, carbon dioxide, and water vapor fluxes in the atmospheric boundary layer, but each was instrumented differently. Fourteen wing-to-wing formation intercomparison runs were conducted during FIFE. They showed good agreement of most parameters even though the craft were flown at not normal airspeeds for this intercomparison. There was good correspondence between the NCAR King Air and NRC Twin Otter over the full wavelength range of 10m to 50km. This data showed that the 15km flight legs of FIFE could give reliable flux data using unfiltered, detrended data. Disagreements in correlated data products were shown to often be the result of analysis techniques, not instrumentation.
