CEMPD/SMOKE: SMOKE v4.8.1 Public Release (January 29, 2021)

SMOKE Digital Object Identifier (DOI): SMOKE-MOVES Integration Tool Development 1. <b>New MOVES RatePerStart (RPS) Mode</b>

• New feature in <b>Movesmrg</b> for users to model Off-Network Start Exhaust and Crankcase Start Exhaust processes that are currently modeled under RatePerVehicle (RPV) mode.
• Unit of RPS emission rate is mass per vehicle-engine start (grams/vehicle-start).
• New "STARTS" activity inventory is required to compute RPS emissions with RPS emission rates.
• RPS_MODE[default: N] : Estimates off-network RPS emissions from engine starts.

2. <b>New Off-Network Idling (ONI) Mode</b>

• New feature in <b>Movesmrg</b> for users to model idling emissions from parking lot, distribution centers and other off-network spaces.
• Previously modeled under RatePerDistance (RPD) mode with roadtypes=1 (off-network) and speedbin=0 (speed=zero).\
• Unit of ONI emission rate is mass per vehicle-idling hour (grams/hour).
• New "IDLING" activity inventory is required to compute ONI emissions with ONI emission rates.
• ONI_MODE [default: N] : Estimates off-network idling emissions from parking, and distribution centers.

New Source Apportionment Regroup Tool

• New Source Apportionment Regroup Tool will allow users to assign existing Source Apportionment (SA)-ready gridded hourly emissions and stack groups files from SMOKE to new SA group IDs.
• Requires the sector-specific SA-ready gridded hourly emissions and stack group files and new regroup mapping input file called <a href="https://www.cmascenter.org/smoke/documentation/4.8/html/ch05s03s13.html"> REGROUP_GROUPS</a>.
• Check out <a href="http://crcao.org/wp-content/uploads/2020/03/CRC-Project-A-119_Final_Report.12March2020.pdf"> the Coordinating Research Council (CRC) A-119 Full Technical Report</a> for the details.
• Download the complete use case package data file for the SA regroup tool from <a href="https://appriver3651013736-my.sharepoint.com/:u:/g/personal/bcarter_crcao_org/EagBTKodLfBCnpQCCdBUBKoBbo8KlKYoDRw-FekHmb11zA?e=UW3s2g"> the CRC Data Share Site</a>.

BEIS v3.7 Enhancements

• New BEIS Emission Factors (BEISFAC) and BELD5 landuse input files are required.
• Latest BEISFAC and North America region BELD5 (1km x 1km) input files for BEIS v3.7 can be found from <a href="https://drive.google.com/drive/u/1/folders/1v3i0iH3lqW36oyN9aytfkczkX5hl-zF0"> the CMAS Data Warehouse</a>.
• Custom BELD5 input file over your modeling domain can be developed using new updated <b>Aggwndw</b> utility program in SMOKE that can optionally aggregate non-mass values with the setting of AGGREGATE_EMIS_YN = N.

Laypoint Updates

• Update to treat new WRF hybrid-vertical coordinate type (-999) as existing sigma (7) coordinate.
• Update to enforce fire bottom plume height starting from surface layer.
• New FIRE_BOTTOM_LAYER_1_YN [Default: Y]: Define the bottom of fire plume as model layer 1.

Smkinven Updates

• Prevent from dropping CEMS hourly NOX and SO2 emissions when all CEMS parameters (e.g., heat input, steam load and gross load) are missing.
• Update to proper handle multiple ORIS and Boiler IDs CEMS sources under the same point source Unit ID.
• PROCESS_MULT_ORIS_UNITS_YN [default: N]: Allows Smkinven to append "__##" to Unit ID to treat them as separate point sources.

Smkmerge and Movesmrg Updates

• SMK_SUB_SECTOR_OUTPUT_YN [default:N]: Generate sub-sector source group emissions output files based on the list of source group ID defined in (<a href="https://www.cmascenter.org/smoke/documentation/4.8.1/html/ch08s10s13.html">SOURCE_GROUPS</a>).

Spcmat and Smkreport Updates

• USE_REF_COUNTY_MAP_YN [default:N]: New feature to assign speciation profiles by reference county based on the inventory-reference county cross-reference input file (<a href="https://www.cmascenter.org/smoke/documentation/4.8.1/html/ch08s09s02.html#sect_input_mcxref">MCXREF</a>).
• Generate correct Smkreport reports for the inventory sources with multiple speciation profiles assigned by GSPRO_COMBO and/or multiple GSREF cross-referencing approaches.
• New speciation profile description (GSPRODESC) input file support in Smkreport. Users can optionally output the speciation profile descriptions to Smkreport "BY SPCCODE" report.</li>

SMOKE4AERMOD Updates

• Added new command "AERMOD ANNUAL" in Smkreport to generate emission helper files for AERMOD model for sectors other than onroad.
• Overall updates across all sectors (e.g., point, area, commercial marine vessel port & underway, and gridded sectors).

Bug fixes

• Various bug fixes since the public SMOKE version 476 release in September 2019
