** Pollutant (NOx) Transport and Propagation Modeling from Stack attached to Diesel Fired Engines at GMR, Basin Bridge Power Plant, Chennai

The project is to study the level of contribution of the facility to the regional air quality.   The study includes meteorological study and air quality dispersion modeling using AERMOD with one year meteorological data.  The study also incorporates the terrain condition as well as taking into consideration of the water bodies near.  The study is to validate the present ambient air monitoring network that is being followed at the facility and to estimate the contribution under different operating conditions.

**Pollutant (NOx) Transport and Propagation Modeling from Stack attached to Diesel Fired Engines at Ascendas International Tech Park, Chennai  

The project is to study the level of contribution of the facility to the regional air quality.   The study includes meteorological study and air quality dispersion modeling using AERMOD with one year meteorological data.  The Metrological data from Sathyabama University and Nugambakkam Meteorology station was used to establish the micrometorological conditions present at the project site. Terrain condition along the 5 km radius of the project site is incorporated in the study.  The study is to validate the ambient air level contributed by the diesel fired engines along the IT Corridor and othe sensitive locations.
