AVERT Tutorial Using AVERT Outputs in SMOKE: Overview
Using AVERT Outputs in SMOKE: Overview
In addition to providing summary estimates of displaced emissions from EE/RE in Excel format, the AVERT Main Module can also produce output files for the Sparse Matrix Operator Kernel Emissions (SMOKE) modeling system.
SMOKE is primarily an emissions processing system designed to create gridded, speciated, hourly emissions for input into a variety of air quality models such as CMAQ, REMSAD, CAMX, and UAM. SMOKE supports area, biogenic, mobile (both onroad and nonroad), and point source emissions processing for criteria, particulate, and toxic pollutants.
AVERT produces 24 output files (one for each month, pre- and post-EE/RE) in ASCII format for use in SMOKE. The files are already in a format recognized by SMOKE called the Continuous Emissions Modeling (CEM) format, which has 16 columns corresponding to the table below (excerpted from the SMOKE v3.6 User’s Manual).
CEM format for individual hour-specific data files:
|A||ORISID||Char (6)||DOE Plant Identification Code (required) (should match the same field in the PTINV file in IDA format)|
|B||BLRID||Char (6)||Boiler Identification Code (required) (should match the same field in the PTINV file in IDA format)|
|C||YYMMDD||Int||Date of data in YYMMDD format (required)|
|D||HOUR||Integer||Hour value from 0 to 23|
|E||NOXMASS||Real||Nitrogen oxide emissions (lb/hr) (required)|
|F||SO2MASS||Real||Sulfur dioxide emissions (lb/hr) (required)|
|G||NOXRATE||Real||Nitrogen oxide emissions rate (lb/MMBtu) (not used by SMOKE)|
|H||OPTIME||Real||Fraction of hour unit was operating (optional)|
|I||GLOAD||Real||Gross load (MW) (optional)|
|J||SLOAD||Real||Steam load (1000 lbs/hr) (optional)|
|K||HTINPUT||Real||Heat input (mmBtu) (required)|
|L||HTINPUTMEASURE||Character(2)||Code number indicating measured or substituted, not used by SMOKE|
|M||SO2MEASURE||Character(2)||Code number indicating measured or substituted, not used by SMOKE|
|N||NOXMMEASURE||Character(2)||Code number indicating measured or substituted, not used by SMOKE|
|O||NOXRMEASURE||Character(2)||Code number indicating measured or substituted, not used by SMOKE|
|P||UNITFLOW||Real||Flow rate (ft3/sec) for the Boiler Unit (optional; must be present for all records or not any records – not yet used by SMOKE)|
