PTEMARB.DAT File - Data Records
The PTEMARB.DAT file contains two types of data records. A set of time-invariant records (see Table
F-18) are read after the header records. These records specify the time-invariant source parameters,
including the source coordinates, stack height, diameter, momentum flux factor, and building data for
sources subject to building downwash. The vertical momentum flux factor may be either 1.0 (full vertical
momentum flux), or 0.0 (no vertical momentum). Use 0.0 to simulate the effect of stack structures like
rainhats. A set of time-varying data follows (see Table F-19). The time-varying records contain the stack
temperature, exit velocity, initial plume size (F y and F z ), and emission rate for each species.
Sample Fortran read statements for time-invariant data records in the unformatted file are:
+)))QLoop over sources
*
* READ(iunit)CID,TIDATA
* READ(iunit)BHT (only if TIDATA(6) = 1)
* READ(iunit)BWD (only if TIDATA(6) = 1)
*
.)))QEnd loop over sources
where the following declarations apply:
CHARACTER*16 CID
REAL TIDATA(8), BHT(36), BWD(36)
Sample Fortran read statements for time-varying data records in the unformatted file are:
+)))QLoop over time periods
