X coordinates (km) of each vertex of the area source on<br />

the meteorological grid<br />

the meteorological grid<br />

The variables in Input Group 14c are entered for each of the "NAR1" area sources. The data for each<br />

source is treated as a separate input subgroup, <strong>and</strong> therefore, must end with an input group terminator<br />

(i.e., !END!). Note that the source number is an optional user comment which is outside of the delimiter<br />

containing the required source data. The data for each source must follow an opening delimiter <strong>and</strong> "X=".<br />

The data for each source is followed by a closing delimiter <strong>and</strong> an input group terminator.<br />

The format of Input Group 14c is shown below.<br />
