SMOKE version 3.5.1 Release Notes

Overview of Updates in SMOKE version 3.5.1

New Source Apportionment feature in SMOKE consists of grouping sources by characteristics (i.e. FIPS code, SCC, and point source information) and then tagging the emissions from those groupings for further analysis in the air quality model. The SMOKE programs Movesmrg and Smkmerge can optionally output the emissions in special files used for later source apportionment processing in air quality models. See detail information from SMOKE v3.5.1 user's guide Chapter 4.4.24.
Enhancement in MOVES RPP (RatePerProfile) processing in SMOKE system: Daily gridded min/max temperatures is used for a better spatial representation of RPP emissions from mobile sources instead of averaged county-specific min/max temperatures.
Movesmrg optionally can output Temporal intermediate hourly emissions files for Smkreport to create time-dependent emissions summary reports.
Updated vertical allocation algorithm when processing pre-computed plume rise variables (i.e., LAY1F, PBOT, PTOP) is used to avoid any discontinuity of plume during the model layer vertical allocations.
New NH3 profile method "BASH_NH3" is added in Gentpro to calculate temporal hourly profiles for livestock ammonia source.

Updated to read new "MOVES_RH_OUTFILE" output file from Met4moves to support daily gridded min/max temperatures in MOVES RPP processing in SMOKE.

Added a new profile method "BASH_NH3" under "PROFILE_METHOD" that allows users to calculate temporal hourly profiles for livestock ammonia sources, and renamed the original AGNH3 method to RC_NH3.

RC_NH3: use the Russell and Cass algorithm to calculate temporal hourly profiles for agricultural ammonia sources
BASH_NH3: Use the algorithm to calculate temporal hourly profiles for livestock ammonia sources: Added a new "AERO_RESISTANCE_VAR" for aerodynamic resistance variable name for the BASH_NH3 method.

Added a new flag "SPEFIFIC_HUMIDITY_YN" that allows users to optionally output specific humidity by temperature bin instead of relative humidity(RH)
Added a new output file "MOVES_RH_OUTFILE" for MOVES runspec_generator script to create RPD and PRV runspec MOVES input files. It contains the reference county-specific average RH, minimum and maximum temperatures by temperature bin and fuel month.
Disabled RH_STR_HOUR and RH_END_HOUR flags. All hour RH values will be used to compute average RH by temperature bin. MIN_NO_RH_BY_TEMPBIN flag to determine number of sources to compute average RH by temperature bins.
Removed AVERAGING_METHOD: [default: DAILY]. No longer support for Monthly averaging method for RPP processing

Added Source grouping option to support source apportionment method in CAMx and CMAQ models
Optionally output hourly emissions (Temporal intermediate output file) using MTMP_OUTPUT_YN. It requires new environment variable "MTMP_INV" as the output filename
Process new gridded min/max daily temperatures for RPP mode processing
Added warning message when there is no activity inventory SCC found in MOVES Lookup tables
Bug fix: Does not look for Jan 1 following year to process Dec 31

New vertical allocation algorithm when processing pre-computed plume rise variables (i.e., LAY1F, PBOT, PTOP) to avoid any discontinuity of plume during the model layer vertical allocations.

Enabling combining VOC and HAPs together for hourly and daily inventories for ORL and FF10 formats.
No longer setting all pollutants to zero when CEM NOx hourly emissions is zero.
Bug fix: Processing FF10_[NONPOINT|POINT]_[HOURLY|DAILY] inventory data files.
Bug fix: Replaced NHAPEXCLUDE_YN flag with SMK_PROCESS_HAPS. NHAPEXCLUDE_YN flag is no longer in use.
