application software


We are designing new training sessions (Winter/Spring 2017) for AERflare-incin and ABflare.


Thank you to those who participated in the feed back survey for the design of the training sessions.

AERtools is a collection of spreadsheet and application programs created for air quality professionals for the calculation of source parameters and ground level concentrations.  The tools were created based upon state-of-the-art engineering considerations of thermodynamics, energy balance, mass balance and practical application of these principles for use with current air dispersion models and methods.









AERflare-incin is the current evolution of ERCBflare and ERCBincin tools.  This tool functions as a stand-alone MS Excel spreadsheet server and database.  The tool accepts user inputs and generates air dispersion modelling source inputs for the U.S. EPA AERMOD dispersion model and steady state source parameters for the CALPUFF air dispersion model.   AERflare-incin can be used to create AERMOD ready input files or can be used as a server to run AERMOD in screening or refined modes and interpret the predictions for Alberta regulatory ambient air quality compliance and well test flaring/incineration applications.  The goal in developing AERflare-incin was to ensure a consistent content, required contents and quality of air quality modelling, reports and applications to AER (Alberta Energy Regulator)  and AEP (Alberta Environment and Parks).


ABflare was developed as a sister tool to AERflare-incin.  Whereas AERflare-incin was developed for screening and refined air dispersion modelling for AERMOD, ABflare was developed for refined dispersion modelling for time-varying source parameters of flare sources for the CALPUFF model.  As a part of the ABflare model development, the CALPUFF model was extended to extend the source types from point, line, volume and area sources to include a flare source.  The flare source in CALPUFF is a time-varying (arbitrary input) file allowing the time variation of height, diameter, velocity, temperature and location of the (effective) point source.  The ABflare tool is used to create the time-varying input file as well as act as a server to assist the creation of CALPUFF input files and assessment of output from this type air quality analysis.  The ABflare tool can be used to create CALPUFF and AERMOD input files.


AERflare-incin v2.06.161027

This version of AERflare contains the latest features and bug repairs.  Some of the features may still contain bugs and we appreciate hearing about all suspected bugs, odd behaviour or suggested improvements and features.


NOTE: the Windows and/or MS Office updates (late October) which caused Excel to crash when AERflare or ERCBH2S was loaded, is now repaired with Windows and/or MS Office (dated November).



spreadsheet only (updated 2017-Jan-15)

- Corrects 64bit declaration (updated 2016-Nov-01)

- Corrected broken links on oSUMMARY page (updated 2016-Oct-28)

- Corrected printout on iTERRAIN, where Row 80 of the page could be over-written if the contour interval was low.

- Corrected printout on iTERRAIN of xyz-distance, where the start index in the contour data array could be calculated incorrectly depending upon the final contour interval

- Corrected iBATCH save of DEM_OUT (rows 56-80, exclusive of flare 0,0), instead of (rows 55-79, inclusive of flare 0,0). (updated 2016-Oct-27)

- Windows 10 Update KB3199209 leads to crash of Excel when AERflare-incin is loaded. (updated 2016-Sep-22)

- Corrected missing calculation for Qmin flammability check for air assisted flaring.

- Corrected bug affecting selection of Incinerator source type dropdown and creating an error message “cannot write to protected area”.

- conditional formatting corrections
