Air quality models are primarily used as a quantitative tool to correlate the emissions and concentration levels found in an area.The United States Environmental Protection Agency (USEPA)has published guidelines on the use of air quality models [1].The CALPUFF model is the preferred model,as ...
An FDDA-assisted model simulation covering a historical air-quality episode is then used as input to CMAQ and other air quality models to study the episode. Nudging FDDA effectively controls model error growth while the model simultaneously produces detailed mesoscale structures which may not be ...
The Guideline on Air Quality Models is used by EPA, state and local permitting agencies, and industry to prepare and review new source permits and state implementation plan (SIP) revisions. The Guideline was revised to adopt a new dispersion model―CALPUFF―as the preferred method for assessing...
CMAQ is an active open-source development project of the U.S. EPA's Office of Research and Development that consists of a suite of programs for conducting air quality model simulations. CMAQ is supported by the CMAS Center:http://www.cmascenter.org ...
The Landfill Gas Emissions Model (LandGEM) is an automated estimation tool with a Microsoft Excel interface that can be used to estimate emission rates for total landfill gas, methane, carbon dioxide, nonmethane organic compounds, and individual air pollutants from municipal solid waste landfills. ...
Models-3 Community Multiscale Air Quality (CMAQ) model aerosol component 1. Model description [1] The aerosol component of the Community Multiscale Air Quality (CMAQ) model is designed to be an efficient and economical depiction of aerosol dynamics ... Binkowski,S Fr...
AERMOD - AERMIC DISPERSION MODEL AERMOD, designed by the AERMIC committee to implement state-of-the-art modeling concepts into the EPA's local-scale air quality models AERMOD, developed as a new platform for regulatory steady-state plume modeling Data Flow In AERMOD Modeling System AERMOD - ...
The Chemical Mass Balance (CMB) air quality model is one of several receptor models that have been applied to air resources management. EPA-CMB8.2 incorporates the upgrade features that CMB8 has over CMB7, but also corrects errors/problems ...
A comprehensive examination is presented of the accuracy and adequacy of air quality models and monitoring data, with particular emphasis on the utility of model predictions and air quality data in assessing the impact of new energy developments on the air resource. (auth) 展开 ...
Air Quality: EPA's 2013 Changes to the Particulate Matter (PM) Standard Introduction On January 15, 2013, the Environmental Protection Agency (EPA) published a final rule in theFederal Registerto strengthen the National Ambient Air Quality Standard (NAAQS) for particulate matter (PM).1The standar...
