Abstract. This study investigates the impact of aerosol hygroscopic growth effect on haze events in Xingtai, a heavily polluted city central part North China Plain (NCP), using large array instruments measuring optical, physical, and chemical properties. Key used measurements made include Raman lidar for atmospheric water vapor content optical profiles, PC-3016A GrayWolf six-channel handheld particle mass meter total particulate matter (PM) that has diameters less than 1 2.5 µm (PM1 PM2.5,...
Abstract. The Taklamakan desert is an important dust source for the global atmospheric budget and a cause of weather in East Asia. characterization region still very limited. To fill this gap, DAO (dust aerosol observation) was conducted April 2019 Kashi, China. Kashi site about 150 km from western rim strongly impacted by aerosols, especially spring time, i.e., May. According to sun–sky photometer measurements, optical depth (at 500 nm) varied range 0.07–4.70, Ångström exponent (between 440...
Precipitation is one of the most important parameters in Earth system but hard to measure. China began develop satellites dedicated precipitation measurements second generation FengYun polar-orbiting meteorological satellite program (FY-3). The first total 2 rainfall missions scheduled, FY-3G, was successfully launched on 16 April 2023 and became world’s third measure with space-borne radar after tropical measuring mission 1997 global measurement core observatory 2014. In this manuscript, we...
Abstract. The North China Plain (NCP) has experienced frequent severe haze pollution events in recent years. While extensive measurements have been made megacities, aerosol sources, processes, and particle growth at urban downwind sites remain less understood. Here, an chemical speciation monitor a scanning mobility sizer, along with suite of collocated instruments, were deployed the site Xingtai, highly polluted city NCP, for real-time submicron (PM1) species number size distributions...
The short-wave infrared Polarization and Multi-Angle Imager (PMAI) onboard Fengyun-3 precipitation satellite is a new spaceborne imaging polarimeter for clouds aerosols, with polarization channels of 1030, 1370, 1640 nm. This study presents detailed description assessment the calibration model PMAI. For radiometric intensity calibration, multiple parameters in are fitted into single coefficient to simplify calibration. Results show that uncertainty full image plane better than 0.02,...
Abstract. The atmospheric mixing layer height (MLH) determines the space in which pollutants diffuse and is thus conducive to estimation of pollutant concentration near surface. study evaluates capability lidar describe evolution then presents a long-term observed climatology MLH diurnal cycle. Detection heights (MLHL MLHL′) using wavelet method based on observations was conducted from January 2013 December 2018 Beijing urban area. two dataset results are compared with radiosonde as case...
Accurate measurement of the radiative properties clouds and aerosols is great significance to global climate change numerical weather prediction. The multi-angle polarization imager (MAPI) onboard Fengyun-3 precipitation satellite, planned be launched in 2023, will provide multi-angle, multi-shortwave infrared (SWIR) channels multi-polarization satellite observation aerosols. MAPI operates a non-sun-synchronized inclined orbit provides images with spatial resolution 3 km (sub-satellite)...
Under the comprehensive reform of its household registration system, China has experienced largest and fastest urbanization process in world since establishment 70 years ago, but with deepening urbanization, cities are facing greater environmental challenges. As total amount urban wastewater discharge increases, condition water pollution nationwide become more severe. Thus, through use dynamic exogenous variable data envelopment analysis (DEA) this research selects employment population...
Abstract An in‐depth understanding of the relationships between ecosystem services (ESs) and socioeconomic (SE) development is an important prerequisite for coordination sustainable regional human–environmental management strategies. In this study, coupling model employed to explore synergistic trade‐off ESs SE factors.The results show that in Yangtze River Economic Belt are currently a stage. At urban scale, synergy water production other functions more than 20% higher systems. The...
Land use change is an important factor affecting the performance of ecosystem services (ESs). Therefore, understanding impact land on ESs great significance for promoting coordination regional human-land relationships. In this study, random forest and cellular automata were used to simulate predict characteristics in Yangtze River Economic Belt, diversified evolution patterns formed combination with China's strategic development needs. The effects habitat suitability analyzed by using a...
Abstract. The hygroscopic growth of aerosol particles is a key factor air pollution because it can significantly reduce visibility. In order to better understand the impact effect on haze events and contributing factors, we made use rich measurements during an intensive field campaign conducted in Xingtai, Hebei province China that has suffered from most serious Northern Plain. Key are Raman lidar ground-based instruments such as GrayWolf 6-channel handheld particle/mass meter for...
The polarization payload onboard Fengyun-3 precipitation satellite (FY-3G) is the first Polarization and Multi-Angle Imager (PMAI) with a shortwave infrared channel in China. Three spectral bands are equipped polarizers : 1030 nm, 1370 nm 1640 nm. For each of these wavelengths, three similar filters associated polarizers, direction third one being at +60° -60° from central one. image band obtained subsequent detector response. To compensate for flight lag, design uses wedge prism to register...
Abstract Detecting supercooled water clouds (SWCs) is essential for enhancing artificial rainfall, preventing aircraft ice accretion, and developing a better understanding of radiative energy balance. The 1.37 μm channel, known as strong vapor absorbing, was made polarized in the multi‐angle imager (PMAI) onboard FengYun‐3G satellite. infight data shown that new channel could be used to detect SWCs. cloudbow observed around 140° scattering angle polarization image, with maximum reflectance...
