Figure 4-1. Geophysical properties of the site of the 1981/1982 Cameron, Louisiana tracer experiment, as gridded for use in the CALMET/CALPUFF simulations. The grid cell size is 200m. Tracer concentrations were measured at the indicated sampler locations. Tracer release locations indicate boat positions used on 2/15/1982 and 2/24/1982, and Platform 28A used for all other periods. Final Report Vol.1 28
All sampler locations are used as receptors, but additional ones are added to increase the density of receptor spacing along the shoreline. Intermediate receptors are placed at approximately 50m intervals, with elevations interpolated from the actual sampler elevations. In this case, all elevations are 1.5m MSL. A total of 380 receptors are used in the CALPUFF modeling. Meteorological Processing Meteorological data files for applying CALMET/CALPUFF to the Cameron study are developed primarily from files used to run OCD4. The “release” meteorology identified for OCD4 is used to construct representative SEA.DAT (over water) and SURF.DAT (over land) input files for CALMET. Cloud observations made at the Cameron shoreline during the study are included in the SURF.DAT file. The SEA.DAT station is placed at Platform 28A, while the SURF.DAT station is placed onshore at (480, 3295). The original OCD4 evaluation files indicate that air temperature and wind speed are measured at 18m for all of the hours. This is true most of the time, but there are periods when data from 10m at the shoreline mast are substituted for the 18m data at Platform 28A. This occurs on: Temperature at 10m 7/**/1981 all hours (platform did not measure air temperature in July) 2/15/1982 all hours 2/17/1982 1300-1400 2/23/1982 1000-1100 Wind Speed at 10m 7/20/1981 all hours 2/15/1982 all hours 2/17/1982 1300-1400 The anemometer height associated with the SURF.DAT wind data during these periods is set to 10m. Because CALMET accepts a single measurement height for the speed and temperature in the SEA.DAT file, that height is reset to 10m whenever the temperature measurement height is 10m. Wind speed is profiled from the actual anemometer height to the temperature measurement height when these are different. Boundary layer parameters computed by OCD are used with Monin-Obukhov similarity profiles to compute the wind speed adjustment. Wind directions used in the OCD4 datasets are those that align the source and the sampler with the peak concentration each hour. This allows the evaluation to focus Final Report Vol.1 29
