A major research plan entitled “Integrated on the ecohydrological process of Heihe River Basin” was launched by National Natural Science Foundation China in 2010. One key aims this is to establish a platform that integrates observation, data management, and model simulation foster twenty-first-century watershed science China. Based diverse needs interdisciplinary studies within plan, program called Watershed Allied Telemetry Experimental Research (HiWATER) implemented. The overall objective...
Core Ideas Heihe was the first basin-scale integrated observatory network established in China. An intensive flux observation matrix experiment conducted. New techniques, e.g., wireless sensor network, matrix, and airborne remote sensing, are used. The is useful land surface processes research. Research on at catchment scale has drawn much attention over past few decades, a number of watershed observatories have been worldwide. River Basin (HRB), which contains second largest inland river...
High levels of HONO have frequently been observed in Chinese haze periods and underestimated by current models due to some unknown sources formation mechanisms. Combining lab-chamber simulations field measurements Xi'an Beijing, China, we found that NH3 can significantly promote via the reduction–oxidation SO2 with NO2 aqueous phase hygroscopic particles (e.g., NaCl). Concentrations formed aerosol showed an exponential increase (R2 = 0.91) under chamber conditions a linear growth two cities....
Abstract Over the past few years, rapid development of machine learning (ML) models for weather forecasting has led to state-of-the-art ML that have superior performance compared European Centre Medium-Range Weather Forecasts (ECMWF)’s high-resolution forecast (HRES), which is widely considered as world’s best physics-based system. Specifically, outperformed HRES in 10-day forecasts with a spatial resolution 0.25 ∘ . However, challenge remains mitigating accumulation errors longer effective...
Objective measurement of the supply-demand ecosystem services and sustainable management has received increasing attention from scientific community general public. This study explored changes in their natural social driving mechanisms using spatial analysis methodologies as well relationship between environmental justice coastal regions China. In this study, service index (ESSDI) was proposed based on provision land development index. Results indicated that although imbalance pattern...
Abstract Emissions of residential coal burning are an important contributor to air pollution in developing countries, but few studies have yet comprehensively characterized the physicochemical properties individual primary particles from burning. Fine emitted eight types with low, medium, and high maturity were collected flaming burn‐out stages a typical stove. Based on morphology composition particles, they divided into six types: organic matter (OM), OM‐S, soot‐OM, S‐rich, metal, mineral...
Black carbon (BC) not only warms the atmosphere but also affects human health. The nationwide lockdown due to Coronavirus Disease 2019 (COVID-19) pandemic led a major reduction in activity during past 30 years. Here, concentration of BC urban, urban-industry, suburb, and rural areas megacity Hangzhou were monitored using multiwavelength Aethalometer estimate impact COVID-19 on emissions. citywide decreased by 44% from 2.30 1.29 μg/m3 following period. source apportionment based model shows...
Abstract Air pollution in megacities represents one of the greatest environmental challenges. Our observed results show that dramatic NO x decrease (77%) led to significant O 3 increases (a factor 2) during COVID‐19 lockdown megacity Hangzhou, China. Model simulations further demonstrate large daytime OH and HO 2 radicals nighttime radical, which can promote gas‐phase reaction nocturnal multiphase chemistry. Therefore, enhanced − SO 4 2− formation was because oxidizing capacity. The PM 2.5...
The mixing state and fractal dimension (Df) of soot particles are two major factors affecting their absorption capacity climate effects. Here we investigated these found in a typical valley the southeastern Tibetan Plateau where wood burning local villages was one source particles. Our motivation revealed Df aging property remote air discussed regional climatic implications. We that 64% total analyzed by number were soot-bearing most them aged with sulfate or organic coating. sequence is...
Abstract According to atmospheric modeling and satellite observations, cold fronts can cause trans‐regional transport (TRT) of haze particles from the North China Plain (NCP) Yangtze River Delta (YRD) in winter. However, compositions aging aerosols during TRT have not been studied. We showed PM 2.5 dominated by organic matter (OM) (30%) secondary inorganic ions (36%) NCP 29% 60% YRD. Following TRT, abundant spherical primary OM (i.e., tarballs) (71% number) mainly residential coal burning...
The bromine atom (Br•) has been known to destroy ozone (O3) and accelerate the deposition of toxic mercury (Hg). However, its abundance sources outside polar regions are not well-known. Here, we report significant levels molecular (Br2)─a producer Br•─observed at a coastal site in Hong Kong, with an average noontime mixing ratio 5 ppt. Given short lifetime Br2 (∼1 min noon), this finding reveals large daytime source. On basis laboratory field evidence, show that observed is generated by...
Skillful subseasonal forecasts are crucial for various sectors of society but pose a grand scientific challenge. Recently, machine learning-based weather forecasting models outperform the most successful numerical predictions generated by European Centre Medium-Range Weather Forecasts (ECMWF), have not yet surpassed conventional at timescales. This paper introduces FuXi Subseasonal-to-Seasonal (FuXi-S2S), learning model that provides global daily mean up to 42 days, encompassing five...
ABSTRACT The distributive characteristics of snow cover and their impacting mechanisms on ground thermal regimes in Northeast China remain evasive because limited systematic studies. In this study, based long‐term ground‐based observational data auxiliary topographic data, geographically weighted regression kriging (GWRK) method the temperature at top permafrost (TTOP) model were used to analyze influences duration (SCD) average depth over SCD (ASD ) Xing'an 1960s–2010s. results show a...
Dryness is a critical limiting factor for achieving high agricultural productivity on China’s Loess Plateau (LP). High-precision, field-scale dryness monitoring essential the implementation of precision agriculture. However, obtaining information with adequate spatial and temporal resolution remains significant challenge. Unmanned aerial vehicle (UAV) systems can capture high-resolution remote sensing images demand, but effectiveness UAV-based indices in mapping heterogeneity across...
Recent observations have increasingly challenged the conventional understanding of atmospheric NH3 and its potential sources in remote environments. Laboratory studies suggest that microdroplet redox generation could offer an alternative explanation. However, key questions remain: (1) Can occur ambient air? (2) Is it restricted by presence specific catalysts? (3) What factors determine efficiency via reactions? We investigate these based on adiabatic-expansion-induced perturbation performed...
Abstract Pollutants during haze and Asian dust storms are transported out of the continent, affecting regional climate hydrological biogeochemical cycles. Understanding physicochemical properties aerosol particles is essential to quantify their impacts. In order determine aerosols before leaving we carried a field campaign from 14 April 2 May 2011 at background site in path outflows. We measured concentrations gaseous pollutants (SO , NO NO, O 3 CO), black carbon (BC), particle number situ...
