TERREL PROCESSOR CONTROL FILE<br />

-----------------------------<br />

TERREL accepts terrain surface elev<strong>at</strong>ion d<strong>at</strong>a from a number <strong>of</strong><br />

digital d<strong>at</strong>a bases and forms grid-cell averages or point-values for<br />

use in particular dispersion modeling systems. For the CALPUFF<br />

system, TERREL produces a gridded terrain file for the MAKEGEO<br />

processor, and it produces a file <strong>of</strong> point-values for discrete<br />

receptors for CALPUFF. Use TERREL one or more times to build the<br />

requested file.<br />

Number <strong>of</strong> Terrain D<strong>at</strong>a Files provided in Subgroup 0b<br />

By default, no d<strong>at</strong>a files are expected, and running TERREL<br />

without input d<strong>at</strong>a files will allow it to complete its set-up<br />

procedures, and report the number <strong>of</strong> d<strong>at</strong>a files needed to cover<br />

the specified modeling domain. This inform<strong>at</strong>ion can be helpful<br />

when assembling the d<strong>at</strong>a files for an applic<strong>at</strong>ion.<br />
