Air quality model (AQM) is an essential tool for management of air quality in near field region of an industrial complex. Model validation study using site specific input data can boost the consistency on accuracy of model’s performance for air quality management. This study describes the validation of CALPUFF and AERMOD for assessment of NOx concentrations in near field region of a steel indus...

ii NOTICE The information in this document is in DRAFT form and is still under review by the U.S. Environmental Protection Agency (EPA) and the Federal Land Managers (FLMs). The draft revisions to the IWAQM Phase 2 recommendations presented herein are still undergoing internal testing to assess their viability for meeting the technical objectives of this reassessment. Some sections are still un...

This study examines environmental impact assessment considering filterable particulate matter (FPM) and condensable (CPM) to improve the accuracy of air quality model. Air pollutants meteorological data were acquired from Korea’s national monitoring station near a residential development area in target district background site. Seasonal emissions PM2.5, including CPM, estimated using California...

A modeling system has been developed relying on plume diffusion theory to yield the upwind source area and emissions responsible for a measured downwind concentration. Three steps comprise this modeling strategy. Application of the MM5 meteorological model to yield a regional wind field, processing of the wind field through the Models-3/CMAQ meteorological processor (MCIP), inversion of the res...

این پژوهش با الهام گرفتن از نتایج یک طرح مطالعاتی کاربردی، رویکرد سلسله­‌مراتبی جهت پیگیری فرایند توسعه تأمین‌کنندگان و حمایت تصمیمات موجود در هر مراحل آن ارائه‌ می‌کند. ابتدا، زمینه‌های تأمین نیازمند سپس واجد شرایط هریک زمینه‌ها به کمک تصمیم‌گیری چندشاخصه بهترین-بدترین مشخص می‌گردند. معیارهای شناسایی نیز مرور مطالعات پیشین بهره‌گیری نظرات خبرگان حوزه‌ی خرید استخراج‌شده‌اند. درنهایت، مدل ریاضی ...

The current study aims at modelling the dispersion of two pollutants, namely CO (carbon monoxide) and SO2 (sulfur dioxide) released from District 7 of Tehran Municiaplity, from 20 main line sources, by means of CALPUFF modeling system. CALPUFF is a non-steady state puff modeling software which employs meteorological, terrain, and land-use data to effectively simulate air pollutants' dispersion ...
