To reduce the uncertainty in analyzing ozone (O3) sensitivities based on observed concentrations of volatile organic compounds (VOCs) and nitrogen dioxide, this study proposed the application of consumed VOC concentrations to establish their nonlinear relationship in the actual atmosphere. These parameters were calculated based on the reaction rates and online observations of VOCs, nitrogen dioxide, and O3concentrations at Deyang, Chengdu, and Meishan in the Chengdu Plain, China, during summer 2019. The nighttime isoprene consumption was maximum at 2.03 ppbv at Meishan. The daytime acetaldehyde consumption was a maximum at 2.68 ppbv at Deyang, possibly due to its higher primary emissions and secondary production and its consumption by both OH radicals and photolysis. When the ratios of the total consumed VOC concentrations to the observed or initial NOx(NOx= NO + NO2) concentrations were 3.51 ppbv ppbv–1or 2.22 ppbv ppbv–1, daytime O3variations reached a maximum of 8.45 ppbv or 7.52 ppbv, respectively. The ratios delineated the VOC-sensitive and NOx-sensitive areas. Over 98% of hourly data were in VOC-sensitive areas at both Chengdu and Meishan, respectively, while over 14% of hourly data belonged to NOx-sensitive areas at Deyang. This provided a more accurate method for assessing real-time O3sensitivity and thus implementing dynamic hierarchical control strategies.

Photovoltaic (PV) power generation in China has experienced promising growth and will further become a significant sector of the power system in the near future. To further utilize the variable uncertain PV resources, the PV power generation resource assessment focusing on a high temporal resolution would greatly assist China in achieving its dramatic solar development goals. In this paper, the installed PV potential of every province in China is measured by the Energy Research Institute of the National Development and Reform Commission based on the radiation intensity and temperature data with a time step of 15 minutes. Thus the real-time PV power output of 31 provinces, along with the assessment results show that China's PV power potential is 4567.0 TWh/year, which is approximately equivalent to 60% of the total social electricity consumption in 2019;as for the spatial distribution, Inner Mongolia, Xinjiang, and Tibet possess the largest PV potential in China, with power generation potential of 1281.6 TWh/year, 576.0 TWh/year, and 394.3 TWh/year, respectively;there are large quarterly and monthly varieties in the availability of PV power generation in each province. There are large monthly and quarterly differences in the temporal availability of PV power generation in each province, with the difference between the highest availability month and the lowest availability month in every province generally being larger than 150%, and the PV output also fluctuates considerably during the day in different seasons in each province. © 2024 IEEE.
