Section 9: CALPUFF NSBC in Input Group 1. The data for each combination (i.e., air-mass name, type of variation, and the QFAC array ) are treated as a separate input subgroup and therefore must end with an input group terminator (i.e., !END!). The data for each source-species combination must follow an opening delimiter and "(cspec)=", where (cspec) is a species name defined in Group 2. The data for each combination is followed by a closing delimiter and an input group terminator (i.e., !END!). If NSBC=0, no scaling factors should be defined here. 9-210

Section 9: CALPUFF Table 9-33 (Concluded) BCON.DAT File Inputs Variable Type Description Sample Values (Input Group 4 - Air-Mass Map) NORTH integer array Air-mass type index for each cell along the northern boundary of the computational grid WEST-EAST integer array Air-mass type index for the first (west) and last (east) cell of one row of the computational grid. Records should progress from north to south, starting with the second row from the 'top', and ending with the next-tolast row from the 'bottom'. SOUTH integer array Air-mass type index for each cell along the southern boundary of the computational grid 7*1,3, ... 1, 2 4,1,8*2, ... (Input Group 5a - Air-Mass Definition) AIRMASS character *12 Air-mass name, used to coordinate inputs regional IAM integer Air-mass index, used to store properties 2 (Input Group 5b - Explicit Time-Varying Air-Mass Properties) IBDAT integer Starting date (YYYYJJJ) 2000153 IBHH integer Starting hour (HH), identified by the time at the END of the hour (00-23 LST) 01 IEDAT integer Ending date (YYYYJJJ) 2000345 IEHH integer Ending hour (HH), identified by the time at the END of the hour (00-23 LST) 00 Data records follow Input Group 5b (after the !END! terminator) 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. Subsequent records of each time period provide the data for each air-mass listed in Input Group 5a. Each record contains the air-mass name (in single quotes), the layer-top (m), and the concentration of each species (units specified by IBCU). 9-211

Section 9: CALPUFF<br />

NSBC in Input <strong>Group</strong> 1. <strong>The</strong> d<strong>at</strong>a for each combin<strong>at</strong>ion (i.e., air-mass name, type <strong>of</strong> vari<strong>at</strong>ion, and the<br />

QFAC array ) are tre<strong>at</strong>ed as a separ<strong>at</strong>e input subgroup and therefore must end with an input group<br />

termin<strong>at</strong>or (i.e., !END!). <strong>The</strong> d<strong>at</strong>a for each source-species combin<strong>at</strong>ion must follow an opening delimiter<br />

and "(cspec)=", where (cspec) is a species name defined in <strong>Group</strong> 2. <strong>The</strong> d<strong>at</strong>a for each combin<strong>at</strong>ion is<br />

followed by a closing delimiter and an input group termin<strong>at</strong>or (i.e., !END!). If NSBC=0, no scaling<br />

factors should be defined here.<br />
