VOLEMARB.DAT File - Data Records<br />

The VOLEMARB.DAT file contains two types of data records. A set of time-invariant records (see<br />

Table F-30) are read after the header records. These records specify the source names, <strong>and</strong> a user-defined<br />

index (read but not used). A set of time-varying data follows (see Table F-31). The time-varying records<br />

contain the source location, its effective height above ground, the elevation (MSL) at the location, the<br />

initial F y <strong>and</strong> F z , <strong>and</strong> the emission rate for each species.<br />

Sample Fortran read statements for time-invariant data records in the unformatted file are:<br />
