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.

PM2.5 mass and βSCAT at 550 nm correlated well only during the post-monsoon season.

PM2.5 mass and multiwavelength βABSATN were not well correlated all year round.

At the study site, using βSCAT, βABS or βATN to quantify PM2.5 mass was unsuitable.
