I was hoping to use newer RWC data (NEI 2020) as the RWC input file to run SMOKE 4.6. I have modified input files in the past to scale or zero out sectors for sensitivities, but when the speciation script scpmat runs, it fails with a bunch of errors regarding NONHAPVOC:
ERROR: No speciation cross-reference available (and no default) for:
Region: _____
SCC: ____ POL: NONHAPVOC
I was wondering if it is possible to run SMOKE with a different RWC input file, as I am currently attempting.
Have you tried a more recent version of SMOKE to see if it makes a difference?
Have you tried running with the script and files that were provided with the 2020 platform?
Based on the spcmat log it looks like there is a mismatch between the inventory and ancillary data. It is typically necessary to pair emissions inventories from a specific platform, such as the 2020 modeling platform, with the ancillary data and parameters provided in the platform package.
Ancillary data and scripts from the 2020 platform are available from the FTP site linked from the platform website:
https://www.epa.gov/air-emissions-modeling/2020-emissions-modeling-platform
At a minimum I recommend retrieving the speciation data (https://gaftp.epa.gov/Air/emismod/2020/ancillary_data/speciation_ge_dat_2020ha2_22sep2023.zip) and the core scripts (https://gaftp.epa.gov/Air/emismod/2020/smoke_2020_platform_core_22sep2023.zip).
In the 2020 RWC script the SMK_PROCESS_HAPS value should be set to “ALL”. The GSREF, GSCNV, and GSPRO will all need to be updated with the versions in the speciation package, identified in the RWC core script. SMOKE 5.0 is included in the core package and is the only version tested the modeling platform. You may or may not be able to process the platform scripts with SMOKE 4.6.
After making these updates please wipe out your existing rwc sector intermediate files and rerun from the beginning.
Thank you both for your input! I only need to run the RWC sector, and I was able to run the 2020 rwc sector within smoke4.6 by modifying the original 4.6 scripts with RWC specific speciation and temporal files from the 2020 rwc script. The only unpredicted error was due to county 46113 being renamed to 46102, so I had to ensure backwards compatibility between files by adding references to the original county 46113 to the 2020 reference files. The 2020 rwc sector output files were merge compatible with the sector outputs from smoke 4.6.
I was hoping to use the new spatial surrogates 135 and 136 for CONUS4K runs. We typically run CONUS4_1332x1008, and I was wondering where I may find these surrogate files.
Thanks again for your help!
The 4km CONUS spatial surrogates are available from the 2020 platform FTP:
