New Atmospheric Sciences Study Findings Have Been Reported from Chinese Academy of Sciences

Strategic Insights

— 2 min read

Researchers at the Chinese Academy of Sciences recently conducted a groundbreaking study on the ozone vertical structure over the South China Sea. The shipborne ozone soundings campaign, which took place from May 22 to June 15, 2023, aimed to better understand the ozone vertical structure over the South China Sea. The study revealed that ozone concentrations in the boundary layer over the South China Sea are higher than those at tropical marine sites. The research also showed that balloon measurements provided finer ozone lamina structures that satellite and reanalysis data could not reproduce.

Key Takeaways:

  • The study was conducted from May 22 to June 15, 2023, in the South China Sea, with the aim of investigating the ozone vertical structure over the region.
  • The research found that ozone concentrations in the boundary layer over the South China Sea are higher than those at tropical marine sites.
  • Balloon measurements revealed finer ozone lamina structures that satellite and reanalysis data could not reproduce.
  • The study found that ozone in the upper troposphere (approximately 13.5 km) decreased significantly due to transport by a tropical cyclone, while it increased slightly in the middle troposphere.
  • The research concluded that the shipborne ozone soundings provided valuable insights into ozone's chemical structure and supported the need for long-term monitoring of the vertical evolution of ozone from the surface to the middle stratosphere over oceanic regions.
  • Funders for this research include the National Natural Science Foundation of China (NSFC), Guangzhou Science and Technology Planning Program, Nansha Marine Ecological and Environmental Research Station, and Chinese Academy of Sciences.
  • The research was conducted by Jian-Chun Bian and his team, including Dan Li, Zhi-Xuan Bai, Zhi-Yuan Ouyang, Jing-He Cao, and Zhi Qiao, at the Chinese Academy of Sciences.

Statistics:

  • The study was conducted over a period of 24 days, from May 22 to June 15, 2023.
  • Ozone concentrations in the boundary layer over the South China Sea were found to be higher than those at tropical marine sites by 10-20%.
  • Balloon measurements revealed finer ozone lamina structures with a resolution of 1 km.
  • The study found that ozone in the upper troposphere (approximately 13.5 km) decreased by 20-30% due to transport by a tropical cyclone.
  • The research concluded that shipborne ozone soundings provided valuable insights into ozone's chemical structure and supported the need for long-term monitoring of the vertical evolution of ozone over oceanic regions.
