Overview

Assessment shows lower ice mass in Southern Ocean mixed-phase clouds, indicating biases in atmospheric models affect climate.

Key Points

  • The reduction in ice mass leads to a smaller radiative effect on surface temperatures and circulation, impacting climate models.
  • A lower concentration of ice nucleating particles improved cloud formation, reducing radiative effect by up to 14 W m −2.
  • Analysis utilized satellite and aircraft observations from the Southern Ocean Clouds field experiment conducted in February 2023.
  • Findings highlight the significance of accurately representing mixed-phase characteristics in climate models.
