TL;DR: In this paper, the authors used a multiple linear regression model to fit ozone to meteorological variables and found that meteorology played a significant but not dominant role in the 2013-2019 ozone trend.
Abstract: . Surface ozone data from the Chinese Ministry of Ecology
and Environment (MEE) network show sustained increases across the country
over the 2013–2019 period. Despite Phase 2 of the Clean Air Action Plan targeting
ozone pollution, ozone was higher in 2018–2019 than in previous years. The
mean summer 2013–2019 trend in maximum 8 h average (MDA8) ozone was 1.9 ppb a −1 ( p ) across China and 3.3 ppb a −1 ( p ) over the North China Plain (NCP). Fitting ozone to meteorological
variables with a multiple linear regression model shows that meteorology
played a significant but not dominant role in the 2013–2019 ozone trend,
contributing 0.70 ppb a −1 ( p ) across China and 1.4 ppb a −1 ( p=0.02 ) over the NCP. Rising June–July temperatures over the NCP
were the main meteorological driver, particularly in recent years
(2017–2019), and were associated with increased foehn winds. NCP data for
2017–2019 show a 15 % decrease in fine particulate matter (PM 2.5 )
that may be driving the continued anthropogenic increase in ozone, as well as
unmitigated emissions of volatile organic compounds (VOCs). VOC emission
reductions, as targeted by Phase 2 of the Chinese Clean Air Action Plan, are
needed to reverse the increase in ozone.

TL;DR: In this article, long-term measurements of aerosol optical depths (AODs) at 440 nm and Angstrom exponents (AE) between 440 and 870 nm made for CARSNET were compiled into a climatology of airborne optical properties for China.
Abstract: . Long-term measurements of aerosol optical depths (AODs) at 440 nm and Angstrom exponents (AE) between 440 and 870 nm made for CARSNET were compiled into a climatology of aerosol optical properties for China. Quality-assured monthly mean AODs are presented for 50 sites representing remote, rural, and urban areas. AODs were 0.14, 0.34, 0.42, 0.54, and 0.74 at remote stations, rural/desert regions, the Loess Plateau, central and eastern China, and urban sites, respectively, and the corresponding AE values were 0.97, 0.55, 0.82, 1.19, and 1.05. AODs increased from north to south, with low values ( 0.60) in central and eastern China where industrial emissions and anthropogenic activities were likely sources. AODs were 0.20–0.40 in semi-arid and arid regions and some background areas in northern and northeastern China. AEs were > 1.20 over the southern reaches of the Yangtze River and at clean sites in northeastern China. In the northwestern deserts and industrial parts of northeast China, AEs were lower (

TL;DR: In this paper, emergency decision making for natural disasters plays an increasingly significant role in improving the capability to respond disasters, and an overview of the EDM theory and methods of natural disasters from the methodological perspective.
Abstract: With the increasing trend of global warming, the frequent occurrences of natural disasters have brought serious challenges to the sustainable development of the society. Therefore, emergency decision making (EDM) for natural disasters plays an increasingly significant role in improving the capability to respond disasters. In this paper, we first elaborate the concept and characteristics of EDM for natural disasters and briefly expound emergency decision contents in different stages of natural disasters. Then, an overview is provided for the EDM theory and methods of natural disasters from the methodological perspective. After that, we give a detailed illustration of the construction of emergency decision support system. Finally, we summarize the main conclusions of the paper and point out the prospect of future researches.
