Technical Abstract: The objective of the boundary layer component of SGP97 (Mahrt, 1999) was to determine the influence of soil moisture on the local surface energy budget, and the effect of mesoscale variability on the development of the convective boundary layer. The NRC Twin Otter and NOAA Long-EZ atmospheric research aircraft each made 27 flux-measuring flights over rural Oklahoma between June 18 and July 17, 1997. Since SGP97 was a multi-scale experiment involving surface, tower, aircraft and satellite measurements, combining data from these various systems (to compute a water vapour budget, for example) requires estimates of the degree of correspondence between the measuring platforms. This paper presents the results of aircraft/tower intercomparisons of energy fluxes made throughout SGP97. A companion paper (Dobosy and MacPherson, 1999) focuses on intercomparisons between the tow flux aircraft.
