Abstract. The aerosol–planetary boundary layer (PBL) interaction was proposed as an important mechanism to stabilize the atmosphere and exacerbate surface air pollution. Despite tremendous progress made in understanding this process, its magnitude significance still have large uncertainties vary largely with aerosol distribution meteorological conditions. In study, we focus on role of vertical thermodynamic stability PBL development by jointly using micropulse lidar, sun photometer,...
The collection of ground measurements for validating remotely sensed crop leaf area index (LAI) is labor and time intensive. This paper presents an automatic measuring system that was designed based on a wireless sensor network (WSN). corn LAI continuously observed from June 25 to August 24, 2012. Approximately, 42 in situ WSN measurement nodes were used 4 ×4 km <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> the Heihe watershed...
Abstract. The urban heat island intensity (UHII) is the temperature difference between areas and their rural surroundings. It commonly attributed to changes in underlying surface structure caused by urbanization. Air pollution aerosol particles can affect UHII through changing (1) energy balance radiative effect (ARE) (2) planetary-boundary-layer (PBL) stability airflow modifying thermodynamic structure, which referred as dynamic (ADE). By analyzing satellite data ground-based observations...
Background: Pesticides have been associated with reproductive disorders, but there is limited research on pesticide exposures and human fertility. Objective: We aimed to investigate the effects of preconception exposure pesticides time pregnancy (TTP) infertility in a general population couples planning become pregnant Shanghai, China. Methods: A total 615 women who were enrolled before conception prospectively followed for 1 y observe their TTP. Preconception assessed by measuring urinary...
Abstract. Convective clouds are common and play a major role in Earth's water cycle energy balance; they may even develop into storms cause severe rainfall events. To understand the convective cloud development process, this study investigates impact of aerosols on by considering influence both topography diurnal variation radiation. By combining texture analysis, clustering, thresholding methods, we identify all two warm seasons (May–September, 2016/17) eastern China based Himawari-8 Level...
The rapid urbanization in China has brought about serious air pollution problems, which are likely to persist for a considerable period as the process continues. In urban areas, spatial distribution of pollutants represented by PM
Urbanization and air pollution are major anthropogenic impacts on Earth’s environment, weather, climate. Each has been studied extensively, but their interactions have not. leads to a dramatic variation in the spatial distribution of (fine particles) by altering surface properties boundary-layer micrometeorology, it remains unclear, especially between centers suburbs metropolitan regions. Here, we investigated variation, or inhomogeneity, quality urban rural areas 35 regions across China...
The urban landscape pattern, which can affect the air pollutants distribution in areas, was significantly changed due to expansion of built-up land. Deeply understanding mechanisms by pattern influence PM2.5 concentration is fundamental for pollution control. However, relationship between land and still unclear at different grid scales seasons. In this study, four metrics were calculated quantify characteristics Nanjing, impact on seasons further analyzed. Results showed that dominant...
Power losses on the upper and bottom IGBTs in half-bridge submodules (HBSMs) are not even when hybrid modular multilevel converters (MMCs) work as inverters, which results a large difference their lifetimes. Since system reliability depends device with lowest lifetime, safe reliable operation of converter will be seriously threatened by devices. To address this issue, power loss distribution problem is studied, effect forward voltage drops on-state resistances conduction analysed....
Oil slick thickness was an important parameter for estimating oil spill volume. Two-beam interference theory could be used to interpret the behavior of reflected and refracted light in slick. A quantitative relationship between spectral reflectance established based on this theory. Some parameters have properties numerical oscillation can ignored practical application. In addition, approximation results showed that two were closely related background water thick Therefore, a model derived...
The hierarchical healthcare system is widely considered to be a desirable mode of the delivery services. It expected that establishment can help provide better and more equal accessibility. However, limited evidence has been provided on impacts This study develops an improved Hierarchical two-step floating catchment area (2SFCA) method, which incorporates variable sizes, distance friction effects utilization efficiency for facilities at different levels. Leveraging 2SFCA various scenarios...
In response to significant shifts in dietary and lifestyle preferences, the global demand for fruits has increased dramatically, especially apples, which are consumed worldwide. Growing apple orchards of more productive higher quality with limited land resources is way forward. Precise planting age identification yield prediction indispensable market terms sustainable supply, price regulation, management. The trees significantly determines productivity, quality, yield. Therefore, we...
The urban heat island (UHI) refers to the land surface temperature (LST) difference between areas and their undeveloped or underdeveloped surroundings. It is a measure of thermal influence built-up area expansion (UBAE), topic that has been extensively studied. However, impact UBAE on LST differences rural (UHIU−R) emerging (UHIU−S) in different seasons seldom investigated. Here, UHIU−S UHIU−R 34 major metropolitan regions across China, spatiotemporal variations based long-term space-borne...
This paper aims to retrieve temporal high-resolution LAI derived by fusing MOD15 products (1 km resolution), field-measured and ASTER reflectance (15-m resolution). Though the inversion of a physically based canopy model using satellite data can produce products, obstacle producing is obvious due low resolution high data. A feasible method combine different source data, taking advantage spatial sensors. In this paper, retrieval was implemented dynamic Bayesian network (DBN) framework. MODIS...
The canopy foliage clumping effect is primarily caused by the non-random distribution of foliage. Currently, measurements index (CI) handheld instruments typically time- and labor-intensive. We propose a low-cost low-power automatic measurement system called Multi-point Linear Array Optical Sensors (MLAOS), which consists three above-canopy nine below-canopy optical sensors that capture plant transmittance at different times day. Data communication between MLAOS node facilitated using ZigBee...
