LNEMARB.DAT File - Data Records
The LNEMARB.DAT file contains two types of data records. A set of time-invariant records (see Table
F-26) are read after the header records, to specify parameters used in modeling all line sources in the file,
and the number of time-invariant names used to identify each line source. A set of time-varying data
follows (see Table F-27). The first record in this group identifies the time period. The second identifies
the number of groups of active line sources. Thereafter, a block of records must be supplied for each
active group. The first of these identifies the number of active lines, and the average characteristics of
this group of active lines. The remaining time-varying records in the block complete the description for
each active line: the character name given to the line, the coordinates of the end-points, the release height,
the elevation of the ground, and an emission rate for each species.
Sample Fortran read statements for time-invariant data records are:
READ(iunit,*)MXNSEG,NLRISE
+)))QLoop over maximum number of lines (NSRC5) comprising all groups

* READ(iunit,*)CID

where the following declarations apply:
