AVERT Tutorial 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:

Position Name Type Description
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)
