Determining the fluctuation of PM2.5 mass concentration and its applicability to Monin–Obukhov similarity

In this manuscript, a method based on the nonlinear relationship between mass concentration of fine-particle and visibility is introduced to obtain the high-frequency mass concentration and vertical mass flux of PM2.5 during a haze pollution process. The high-frequency sampling was obtained using a...

Description
Summary:In this manuscript, a method based on the nonlinear relationship between mass concentration of fine-particle and visibility is introduced to obtain the high-frequency mass concentration and vertical mass flux of PM2.5 during a haze pollution process. The high-frequency sampling was obtained using a visibility meter upgraded by our research group. To make the results more reliable, we restricted the service conditions of this method, that is, RH
