The Elevpoint program can select elevated and/or PinG sources as needed for some air quality models and configurations. You must use the Elevpoint program in the following cases:
You are running UAM or CAMX including elevated point sources and/or PinG sources.
You are running CMAQ and want to select specific elevated sources or want to model with the PinG capability.
The following steps must be taken to use Elevpoint:
Create a PELVCONFIG file.
The PELVCONFIG file is the Elevpoint input file that controls what sources will be selected as elevated and/or PinG. Chapter 8, SMOKE Input Files explains the file format for this file and how to use this format. A example PELVCONFIG file provided with SMOKE (in the nctox case PTDAT
Update Assigns file to use the correct name of the PELVCONFIG file.
Set RUN_ELEVPOINT to Y in point source run script.
If using PinG sources, set SMK_PING_METHOD to 1 in point source run script (otherwise, set to 0).
If selecting specific elevated sources, set SMK_ELEV_METHOD to 1 in point source run script (otherwise, set to 0).
See model-specific settings in Section 4.4.19, “Model for CMAQ” and Section 4.4.20, “Model for UAM and CAMX”.
