Elevated ground-level ozone (O3), which is an important aspect of air quality related to public health, has been causing increasing concern. This study investigated the spatiotemporal distribution O3 concentrations in China using a dataset from Chinese national monitoring network during 2013-2015. research analyzed diurnal, monthly and yearly variation both sparsely densely populated regions. In particular, 6 major cities were selected allow discussion variations levels detail, Beijing,...
Abstract Air pollution has aroused significant public concern in China, therefore, long-term air-quality data with high temporal and spatial resolution are needed to understand the variations of air China. However, yearly quality six pollutants still unknown for China until now. Therefore, this paper, we analyze 366 cities across mainland during 2015–2017 first time best our knowledge. The results indicate that annual mean mass concentrations PM2.5, PM10, SO 2 , CO all decreased year by...
Investigate the effect of long-term COVID-19 on maternal and fetal complications. A retrospective cohort study was conducted. total 623 pregnant women who delivered in Kunming First People's Hospital from November 1, 2022 to July 31, 2023 were selected. By employing statistical methods, we compared associations between complications with acute during pregnancy, COVID-19, non-COVID-19 women. In final samples, there 209 72 342 without COVID-19. The epidemiological clinical characteristics all...
Due to biomass burning and coal combustion, heavy fine particulate matter (PM2.5) pollution frequently occurs in Northeast China, threatening the health of more than 117 million inhabitants. Although meteorological conditions have always been considered key factors accumulation dilution PM2.5 pollution, their exact contribution China is still highly uncertain. Applying multiple regression analysis observational data, we identify wind speed, temperature inversion, height planetary boundary...
The dynamic characteristics of biomass burning aerosol originated from South Asia are investigated in this research using nearly 9 years POLDER/GRASP satellite dataset. remote sensing data can provide global, repeatable, various, and sufficient real-world information even the ocean region, which can't be offered by ground measurement, laboratory observation or model simulation. MODIS thermal anomalies/fire dataset HYSPLIT backward trajectory applied to search burning. could transport...
When a precise quantitative analysis of satellite measurements over bodies water is required, the bidirectional effects water-leaving radiance must be considered. The reflectance distribution function (BRDF) used to estimate directional dependency radiance. Previous research on BRDF has focused oceanic waters; few studies turbid inland waters have been conducted. In this article, using multi-angle MISR measurements, five semi-empirical models (MAG2002, Lee2004, Park-Ruddick 2005,...
The regional transmission characteristics as well the local emission and external contribution of fine particulate matter in eastern North China Plain were investigated using multisource data. Himawari-8 aerosol optical depth can represent whole layer air pollution situation; hourly used to reconstruct route horizontal transmission, speed was calculated compared with near-surface wind speed. A case study conducted on 22 September 2019 showed pollutant mainly transmitted from Tangshan Dezhou,...
High spatial resolution and broad coverage data on fine particulate matter (PM2.5) are of great significance to estimating the exposure PM2.5. However, this type is currently very limited worldwide. In addition, COVID-19 pandemic in China, starting January 2020, may have led significant variations PM2.5 concentrations. To identify causes concentrations before after from 23 March 24 during 2018–2020, article, a geographically weighted regression model with 1 km covering all mainland China was...
