Project Details:

Duration: 3 years (2019-2022)


1.Develop a satellite-based PM2.5 database at high-resolution (1-km) for air quality management in India (completed)

2.Identify the local hotspots, regional air sheds and long-term trends in air quality (ongoing)

3.Facilitate the expansion of the ground-based network (ongoing)

4.Explore the use of Indian geostationary AOD data for PM2.5 monitoring
