MERRA-2 PM2.5 Species Show Variable Agreement with Ground Data in India

Across three Indian sites, MERRA-2 PM2.5 species showed variable agreement with in-situ measurements. Organic carbon varied, sulfate was underestimated, while dust and sea-salt were consistently overestimated.

This study performed the first species-wise validation of MERRA-2 PM2.5 components against year-long (2019) in-situ measurements at Bhopal, Mesra, and Mysuru in India.

The abstract focuses on the study's findings regarding MERRA-2 PM2.5 species validation; it does not provide personal how-to steps.

This study conducted a species-wise validation of MERRA-2 PM2.5 components using year-long (2019) in-situ measurements at three distinct Indian sites. The authors note that ground-based aerosol speciation data for India is generally limited.
