Section 9: CALPUFF values in time provided in Input Group 5. Note that the temporal variation factors are specific to both the species and the air mass. Input Group 2 names the six species that will be emitted along the boundary of the computational domain. Input Group 3 defines the properties of each air-mass that is either constant, or that uses the factored time variation. In subgroup 3a, each air-mass is given a name and an index, followed by the thickness of the layer associated with the air-mass, and the concentration of each species. The name is used to identify airmass properties in subsequent sections of the file, and the index is used to associate each air-mass type with specific cells along each boundary of the domain. Concentrations are entered in the order defined in Input Group 2. Here we have used generic names to suggest the characteristics of each air-mass, and have provided concentrations for each species. This is only intended to illustrate the structure of the BCON.DAT file, and should not be interpreted as typical values suitable for any application. Subgroup 3b provides the temporal variation factors for the number of species/air-mass combinations indicated in Input Group 1 (NSBC). Only SO 2 for each of three air-masses (clean, urban, and model) is given a temporal variation here. Input Group 4 assigns the air-mass types to cells along each boundary, using index values assigned in subgroups 3a and 5a. All cells along the north boundary and the south boundary are assigned to names NORTH and SOUTH, respectively. The cells along the west and east boundaries are entered in pairs, assigned to the variable name WEST-EAST. All of these assignments should be oriented to produce a "map-like" representation of the domain, with north at the top. Input Group 5 defines any remaining air-mass types with properties that may vary hourly. Subgroup 5a assigns the air-mass name and index, and subgroup 5b identifies the time-period that is included in the data records. The input group terminator (!END!) for 5b must be followed immediately by the data records. The first record of each time period defines the range of hours for which the concentration data are valid by listing the beginning date(YYYYJJJ) and hour(HH), and the ending date and hour. The hour is denoted by the time at the end of the hour (00-23 LST). For example, a 3-hour period would be: 1987056 23 1987057 01 and a 1-hour period would be: 1987056 23 1987056 23 Subsequent records of each time period provide the data for each air-mass. Each record contains the airmass name (in single quotes), the layer-top (m), and the concentration of each species (units specified by IBCU). 9-198
