Imported air pollution has a significant impact on urban quality. Relevant studies have shown that many events are not resourced by local emissions but imported from surrounding areas transported across regions. The prevention and control of is very necessary. However, the existing supervision quality mostly relies ground monitoring stations, which extremely limited in time space, cannot satisfy continuous time-space research. Therefore, aiming at problem control, this paper used MERRA-2...
Methane is the world's second largest greenhouse gas after carbon dioxide, accounting for about one-sixth of total emissions. Due to development animal husbandry, dioxide and methane produced in process husbandry breeding have gradually become one important sources effect. The research emissions from great significance sorting out gases. This paper aimed at Hebei Province, using TROPOMI sensors onboard Sentinel-5P, TANSO-FTS GOSAT observation data, related ground station data. main content:...
Geostationary satellites have the capability to offer AOD products with a higher frequency of observation within given period, thus improving geographical coverage averaged compared polar satellites. Moreover, geostationary is more reflective average aerosol load as derived from orbit Despite this, there still an absence comprehensive research on comparative representativeness mean and satellites, most current only focuses retrieval accuracy. This paper compares released by Advanced Baseline...
Methane CH <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">4</inf> ) is the second largest greenhouse gas in world after CO xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> . emissions contribute 16% of world's gases. Although global CH4 are much lower than carbon dioxide emissions, their warming potential (GWP) over 100 years 28-36 times greater that dioxide. Using satellites to observe methane an effective means. This paper aimed at Hebei...
Imported air pollution has a significant impact on urban quality. Many events are not caused by local emissions, but the transport of pollutants from surrounding areas. Therefore, it is very necessary to prevent and control imported pollution. However, existing supervision quality mostly relies ground monitoring stations, which extremely limited in time space. In this paper, MERRA-2 data used grasp more macroscopic perspective, combined with station meteorological data, transmission route...
In this paper, surface-level ozone in China was estimated by using the source-sink analysis and machine learning model. By analyzing source sink of surface ozone, it is clear that mass concentration influenced background value, regional local chemical generation, deposition, removal Interregional transport comprehensively. Then, light gradient boosting (LGBM) model used to integrate various corresponding satellite-based variables, numerical model-based meteorological variables land obtain...
Based on the data of air quality monitoring stations and high-resolution remote sensing product in Xuzhou City, atmospheric pollutants 2020 2021 were analyzed. The modified A-values method model simulation used to estimate remaining environmental capacity (RAEC) PM <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">10</inf> xmlns:xlink="http://www.w3.org/1999/xlink">2.5</inf> Xuzhou, Jiangsu Province. results show that excessive are main problems...
In this paper, surface ozone in China were estimated by the Geographically and Temporally Weighted Regression model with its precursors AOD data. Based on GTWR model, was time, space, AOD. Taking August 1, 2022 as an example, it analyzed confirmed about feasibility of data estimating mass concentrations.
Aerosol Optical Depth (AOD), quantifying the amount of aerosol in atmosphere, is widely regarded as a crucial indicator for research on atmospheric physics and regional air quality. At present, inversion AOD from observation satellite remote sensing sensors has become main technology large-scale monitoring load. The Huaihai Economic Zone connecting belt two key areas governance (the Yangtze River Delta Beijing-Tianjin-Hebei region, China), it been suffering pollution many years few studies...
Dust as a kind of atmospheric pollutants, its harm are gradually being paid attention to. However, most the existing supervision dust relies on ground monitoring sites, which has strong spatial limitations. In this paper, high-resolution remote sensing images used to identify regional sources, can at more macroscopic level from “plane”. At same time, particulate emission inventory was established based multi-source data, and then is quantified. This paper takes Quanshan District, Xuzhou...
