Abstract: Long term exposure to fine particulate matter or PM2.5 poses the risk of respiratory and cardiovascular diseases such as COPD, ALRI, ischemic heart disease etc. Therefore, it is essential to investigate the Spatio-temporal variation of particulate matter concentration on a local and regional scale for environmental health assessment. However, such estimates are limited to the number of ground air quality monitoring stations available and their limited spatial coverage. In the above backdrop, Aerosol Optical Depth (AOD) has been widely used as a key indicator in the measurement of particulate matter concentration as it quantifies the aerosol load in the atmosphere. Satellite-based sensor observation is the primary method of AOD retrieval, due to its extensive spatial coverage, even over remote regions. However, AOD and PM concentrations can be correlated only after correcting for the local and regional meteorological parameters, land-use variables etc. Therefore, research on correlating air pollution with public health in India is also focused on the development of an appropriate AOD-PM relationships by overcoming the inherent AOD retrieval challenges like data gaps due to cloud contamination, data merging, data fusion etc. In the above backdrop, this talk would focus on the current advances, limitations, and challenges in the AOD products and AOD-PM relationship and the application of this study to my ongoing research in Bengaluru.
