5">We report PM2.5 mass and its optical properties over a National Park in Bhopal, India.
- •
Median Angström exponent was 0.65 suggesting significant dust contribution to PM2.5.
- •
5">PM2.5 mass and βSCAT at 550 nm correlated well only during the post-monsoon season.
- •
PM2.5 mass and multiwavelength βABS/βATN were not well correlated all year round.
- •
5">At the study site, using βSCAT, βABS or βATN to quantify PM2.5 mass was unsuitable.
