Beschreibungen/Notizen

• Marshall et al evaluate and test the performance of the Eta Model and demonstrate its impacts on the diurnal cycle of the modeled planetary boundary layer. Operational Eta Model output from summer 1997 are evaluated against the unique observations of near-surface and subsurface fields provided by the Oklahoma Mesonet. Results indicate a severe positive bias in top-layer soil moisture, which were significantly reduced in 1998 by a change in the initialization technique. Moreover, net radiation was overestimated, largely because of a positive bias in the downward shortwave component.
