Estimating anthropogenic CO2 emissions from satellite observations contributes to transparency in reporting. In this study, we proposed a method for calculating using Orbiting Carbon Observatory-2 (OCO-2) XCO2 (the column-averaged dry-air mole fraction) observations. We identified local plume enhancements on the OCO-2 track and retrieved through minimizing difference between enhancement simulated by Gaussian model based emission rates provided Open-Data Inventory Anthropogenic Dioxide...
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:...
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...
It is very essential to resolve the issues of atmospheric ozone pollution and health impact evaluation about high spatial resolution accurate near-surface concentration. Nevertheless, existing remotely-sensed products could not meet demands monitoring. For this purpose, study using surface precursor (the nitrogen dioxide concentration formaldehyde concentration) data developed an improved geographically temporally weighted regression (IGTWR) method estimate This calculated a generalized...
Accurate near surface ozone concentration calculation with high spatial resolution data is very important to solve the problem of serious pollution and health impact assessment. However, existing remotely sensed products cannot meet requirements monitoring. In this study, O 3 (at 30 km resolution) was extracted from daily TROPOMI profile products. Meanwhile, study improved downscaling algorithm based on mutual information applied it mapping in China. Combined (with 5 obtained by using Light...
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...
This paper calculates the Air Quality Index (AQI) in Xuzhou from 2018 to 2020 and analyzes its annual monthly changes air quality determine month of severe pollution. Through AQI calculation interpolation analysis different locations Xuzhou, conditions regions are determined. HYSPLIT backward trajectory model, cluster masses December is carried out. Combined with PM2.5 concentration data released every hour by State Control Station, PSCF CWT methods used potential sources pollution regions....
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.
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...
