Executive Summary :

Most Indian cities are highly polluted with Respirable Suspended Particulate Matter and Fine Particulate Matter and have concentrations that are well above the air quality standards. In this context, atmospheric chemical models can play a pivotal role in the assessment of air quality and strategic planning for emission reduction. temporal scales. The main objectives of the proposed project are (i) to evaluate performance of a particular chemical transport model called WRF chemical transport model for its capability to simulate meteorological fields involving sensitivities towards various parameterization schemes, (ii) to simulate the aerosol distribution over Delhi NCR using WRF-Chem with sensitivity analysis towards different chemical mechanisms and performance evaluation thereafter using available in-situ observations, (iii) to quantify the relative contributions of various emission sources to total aerosol loading in Delhi NCR using different emission inventories with WRF-Chem.
