Rapid warming in the Arctic has a huge impact on global environment. Atmospheric brown carbon (BrC) is one of least understood and uncertain agents due to scarcity observations. Here, we performed direct observations atmospheric BrC quantified its light-absorbing properties during 2-month circum-Arctic cruise summer 2017. Through observation-constrained modeling, show that BrC, mainly originated from biomass burning mid- high latitudes Northern Hemisphere (∼60%), can be strong agent region,...
Abstract. A severe dust storm event originated from the Gobi Desert in Central and East Asia during 2–7 May 2017. Based on Moderate Resolution Imaging Spectroradiometer (MODIS) satellite products, hourly environmental monitoring measurements Chinese cities Asian meteorological observation stations, numerical simulations, we analysed spatial temporal characteristics of this as well its associated impact Asia-Pacific region. The maximum observed PM10 (particulate matter with an aerodynamic...
Abstract. Black carbon aerosols play an important role in climate change because they directly absorb solar radiation. In this study, the mixing state of refractory black (rBC) at urban site Beijing early summer 2018 was studied with a single-particle soot photometer (SP2) as well tandem observation system centrifugal particle mass analyzer (CPMA) and differential mobility (DMA). The results demonstrated that mass-equivalent size distribution rBC exhibited approximately lognormal median...
Abstract. Black carbon aerosols play an important role in climate change by absorbing solar radiation and degrading visibility. In this study, the mixing state of refractory black (rBC) at urban site Beijing was studied with a single particle soot photometer (SP2), as well tandem observation system centrifugal mass analyzer (CPMA) differential mobility (DMA), early summer 2018. The results demonstrated that mass-equivalent size distribution rBC exhibited approximately lognormal median...
Abstract. The effective density (ρeff) of refractory black carbon (rBC) is a key parameter relevant to its mixing state that imposes great uncertainty in evaluating the direct radiation forcing effect. In this study, tandem differential mobility analyzer–centrifugal particle analyzer–single-particle soot photometer (DMA–CPMA–SP2) system was used investigate relationship between and rBC particles during winter 2018 Beijing megacity. During experiment, aerosols with known diameter (Dmob) ρeff...
Abstract. The variability of the mixing state refractory black carbon aerosol (rBC) and corresponding complicated light absorption capacity imposes great uncertainty for its climate forcing assessment. In this study, field observations using a single-particle soot photometer (SP2) were conducted to investigate rBC under different meteorological conditions at rural site on North China Plain. results showed that hourly mass concentration during observation periods was 2.6±1.5 µg m−3 average,...
The mixing state of black carbon aerosols (BC) has the largest uncertainty for climate forcing evaluation. In this study, a tandem observation, combining centrifugal particle mass analyzer (CPMA) and single soot photometer (SP2), was conducted to investigate BC in coastal city eastern China. First, particles with specific masses (1.0 fg, 2.1 4.5 9.7 20.1 fg) were selected using CPMA consecutively measured by SP2 determine corresponding (MBC) particle. ratio (MR) coating matter core used...
Abstract. Depolarization ratio (δ) of backscattered light is an applicable parameter for distinguishing the sphericity particles in real time, which has been widely adopted by ground-based lidar observation systems. In this study, δ values and chemical compositions both PM2.5 (aerodynamic diameter less than 2.5 µm) PM10 10 were concurrently measured on basis a bench-top optical particle counter with polarization detection module (POPC) continuous dichotomous aerosol speciation analyzer...

Abstract. East Asia is suffering from severe air pollution problems due to intensive anthropogenic emissions and natural mineral dust aerosols. During transport, the aerosol particles undergo complex mixing processes, resulting in great impacts on regional quality, human health climate. In this study, we conducted a long-term observation using an optical particle counter equipped with polarization detection module (POPC) at urban site Beijing. Mass concentrations of both PM2.5 PM10 estimated...

Abstract. While global streamflow reanalysis has been evaluated at different spatial scales to facilitate practical applications, its local performance in the time–frequency domain is yet be investigated. This paper presents a novel decomposition approach evaluating by combining wavelet transform with machine learning. Specifically, time series of and observation are respectively decomposed then approximation components against those observed streamflow. Furthermore, accumulated effects...
