Abstract
Twelve‐hour daytime totals of surface sensible heat flux were estimated using geostationary satellite measured surface “skin” temperatures and models of the land surface and the planetary boundary layer for 4 days in August 1989 at the First International Satellite Land Surface Climatology Project (ISLSCP) Field Experiment site. During this period in August a rapid “dry down” occurred in which daytime surface sensible heat flux totals, as estimated from the surface flux measurements, rose from approximately 2–4 MJ m−2 to 6–9 MJ m−2 within the span of a few days. In this period the daytime surface temperature range as measured from the geostationary satellite rose by several degrees Celsius. The standard errors of estimate comparing satellite‐derived sensible heating totals with surface measurements were 0.93 and 1.43 MJ m−2, respectively, using surface roughness length estimates of 1 and 5 cm in the planetary boundary layer model.
