Article Synopsis
- Researchers measured iodine concentrations in rainwater across several locations in Argentina, spanning latitudes from 25° S to 55° S.
- They found iodine levels significantly higher than what would be expected from natural sources and past nuclear tests.
- The elevated iodine is likely due to releases from nuclear fuel reprocessing plants in the Northern Hemisphere affecting the Southern Hemisphere's environment.
A comprehensive analysis of the temporal evolution of tropospheric ozone in Antarctica using more than 25 years of surface ozone and ozonesonde measurements reveals significant changes in tropospheric ozone there. It shows a positive trend in ozone at the surface and lower and mid-troposphere, but a negative trend in the upper troposphere. We also find significant links between different climate modes and tropospheric ozone in Antarctica and observe that changes in residual overturning circulation, the strength of the polar vortex, and stratosphere-troposphere exchange make noticeable variability in tropospheric ozone.
