4.4.14. Use Elevpoint for selecting elevated and PinG sources

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:

The following steps must be taken to use Elevpoint:

  1. 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 directory) contains additional instructions on setting up this file.

  2. Update Assigns file to use the correct name of the PELVCONFIG file.

  3. Set RUN_ELEVPOINT to Y in point source run script.

  4. If using PinG sources, set SMK_PING_METHOD to 1 in point source run script (otherwise, set to 0).

  5. If selecting specific elevated sources, set SMK_ELEV_METHOD to 1 in point source run script (otherwise, set to 0).

  6. See model-specific settings in Section 4.4.20, “Model for CMAQ and MAQSIP” and Section 4.4.21, “Model for UAM, REMSAD, and CAMX.
