Development and Evaluation of the Offshore and Coastal Dispersion Model

摘要: The Offshore and Coastal Dispersion (OCD) model has been developed for the Minerals Management Service (MMS) to determine impact of offshore onshore emissions from point sources on air quality coastal regions. Constructed framework EPA guideline MPTER, OCD incorporates overwater plume transport dispersion as well changes that occur crosses shoreline. Hourly meteorological data are needed both locations, including wind direction speed, mixing height, temperature relative humidity, sea surface temperature. Observed turbulence intensities preferred by but not mandatory. Building downwash rise incorporated into similar their use in Buoyant Line Point Source (BLP) model. Partial penetration elevated inversions is treated using Briggs’ coefficients proportional intensities. A virtual so...
