4.4 Recommendations A minimum σ v for overwater cells should be introduced in CALPUFF so that a value appropriate to overwater dispersion (e.g. 0.37 m/s) can be applied independently of the minimum used over land. The computed Lagrangian timescale approach for lateral dispersion, based in part on the SCIPUFF formulation, leads to unacceptably large overpredictions in CALPUFF and this draft option should be removed at this time. The COARE overwater flux module should be selected in place of the previous OCD-based model. The standard COARE option (no shallow water adjustment or wave model option) appears suitable to these coastal datasets, and there is little performance sensitivity among these options. The SEA.DAT format should allow wind and air temperature measurement heights to be different. The Batchvarova-Gryning convective mixing height option in CALMET was tested in the Oresund dataset and showed promising improvements in model performance. The Batchvarova-Gryning scheme should be tested further in a wide variety of operational simulations for possible general use as the mixing height default option in CALMET. Turbulence advection should be formulated for general use and implemented in the CALMET/CALPUFF system. A re-analysis of these evaluation datasets should be conducted once CALMET/CALPUFF Version 6 becomes available. The ability of this version to use time steps shorter than one hour will facilitate evaluations with the Gaviota and Carpinteria 30-minute datasets, and allow the full set of measurements to be used at all sites. Although the modeling system will use a one-hour time step operationally, evaluations at shorter time steps may allow a better integration of the tracer concentrations and meteorological measurements in both space and time.
