Budget analysis of FIFE-1987 sonde data.

Mean thermodynamic profiles are presented for the daytime convective boundary layer evolution for three groups of sunny days in late June and early July, August, and October using data from the First International Satellite Land Surface Climatology Project (ISLSCP) Field Experiment (FIFE) 1987 Kansas experiment. Budget models for the mixed layer evolution and the boundary layer rise are used to estimate the boundary layer top entrainment parameter. A value of AR = 0.44 ± 0.21 is found for the mean ratio of the inversion level virtual heat flux to the surface virtual heat flux.
