One of the primary aims of the Convection and Precipitation/Electrification (CaPE) experiment held at NASA Kennedy during 1991 was to correlate the sensible and latent heat flux from the vegetation canopy on Merritt Island with satellite imagery of the development and maturation of the thunderstorms which grow over Kennedy. The sensing systems which were used to collect surface observations of radiation, sensible heat flux, latent heat flux, and soil heat flux at two locations on Merritt Island. The observing systems which were built are called Surface Radiation and Energy Budget Systems (SREBS) and are integrated observing platforms comprised of five subsystems: the Bowen ratio subsystem; the radiation subsystem; the soil subsystem; the meteorological subsystem; and the electronics subsystem. Using both of the SREBS assembled, a complete picture was obtained of the distribution and partitioning of the various components in the surface energy budget at two sites during CaPE.
