F.13 Subgrid Scale Coastal Boundary Data File (COASTLN.DAT) CALPUFF contains an option to treat subgrid scale coastal effects such as the development of a Thermal Internal Boundary Layer (TIBL) within an individual grid cell. The subgrid scale coastal module is controlled by the MSGTIBL variable in Input Group 2 of the control file. If MSGTIBL = 1, CALPUFF will introduce a subgrid scale TIBL along a coastal boundary specified in an external file (COASTLN.DAT) when appropriate meteorological conditions exist. The COASTLN.DAT file contains a set of points that serve to define the coastline. Multiple coastlines (up to "MXCOAST", see the PARAMS.PUF file) are allowed within a single file. The COASTLN.DAT file is a sequential, formatted data file (see Table F-44 for an example) consisting of two types of records: a single header record and a variable number of sets of data records. Each set of data records includes a record indicating the location of the water body relative to the coastline (i.e., left or right of the line as one travels in the direction of the data points in the file) and a variable number of records containing the coordinates of each point defining the coastline.
