چکیده
The visibility in the Sichuan Basin (SB) was worse than that North China Plain (NCP) for same level of PM2.5. One well-known reason is aerosol extinction enhancement due to hygroscopic growth SB stronger NCP because relative humidity (RH) higher NCP. However, under PM2.5 and RH levels. volume efficiency (VEE) kept between 7 8 different SB, while VEE increased from 4.6 7.2 when 20 180 μg/m3 difference resulted particle number size distributions. Our research demonstrates an important factor influences provides new insight into impairment SB.
