Summary: This study focused on the trends and meteorological contributions of surface ozone (O-3) pollution in the coastal region of Southeast China. It was found that meteorological conditions, such as relative humidity, boundary layer height, solar radiation, and cloud cover, played important roles in O-3 variability. The weakening southwest winds and increased anti-cyclone systems under climate change were identified as factors that could increase surface O-3 levels. This study provided valuable insights into the meteorological drivers of O-3 pollution in relatively clean areas and highlighted the challenges of mitigating O-3 pollution under global climate change.

Summary: Food recognition is important for food choice and intake, and can support various food-oriented vision tasks. In this paper, we introduce Food2K, the largest food recognition dataset, and propose a deep progressive region enhancement network for food recognition. Experimental results on Food2K demonstrate the effectiveness of our proposed method, and its better generalization ability in various tasks. Food2K can be further explored for more food-relevant tasks and serve as a benchmark for large-scale fine-grained visual recognition.

Summary: The study evaluates the potential for hybridization of existing wind parks in Portugal with solar photovoltaic generation, showing high potential for increasing the share of variable renewable energy sources with minimal energy curtailment. The interior regions of central and northern Portugal exhibit the highest and most consistent levels of complementarity between wind and solar resources, allowing for large-scale exploration and extension of hybrid renewable power plants. Portugal's favorable weather conditions enable the concept of hybrid power plants to be widely explored and replicated for increasing the penetration of renewable energy in electrical power systems while minimizing overall costs.

Summary: The use of wind and solar power has been growing in recent years and is expected to continue increasing in the future. However, maintaining a continuous balance in power systems with larger amounts of renewable energy poses challenges. This article aims to describe and compare the challenges and future possibilities in six different systems to achieve continuous balance in the presence of variable renewable power production. Understanding how these systems plan to handle continuous balancing is crucial for developing a carbon dioxide-free electricity system in the future. The systems included in the overview are the Nordic synchronous area, the island of Ireland, the Iberian Peninsula, Texas (ERCOT), the central European system, and Great Britain.

Summary: The wind generation share in European bidding zones is affecting the market value of wind power, leading to lower prices in day-ahead markets. To mitigate this decrease, diversification measures and demand flexibility measures can be employed instead of investing in energy storage. This article provides examples of such measures from European and USA studies conducted under the international collaboration of IEA Wind TCP Tasks 25 and 53.
