Short summary
Temporal variation in the hygroscopicity and its correlation with the mixing state of ambient BC particles were studied using a HTDMA–SP2 system. Secondary organic carbon formation and condensation of nitrates were mainly responsible for the changes of hygroscopicity of BC particles during daytime and nighttime, respectively. Different atmospheric aging processes led to the change of BC particles' mixing states, which play a fundamental role in determining their hygroscopicity.
Temporal variation in the hygroscopicity and its correlation with the mixing state of ambient BC...
