First ACP Letter: The value of remote marine aerosol measurements for constraining radiative forcing uncertainty

28 August 2020

We are proud to announce that ACP has just published its first ACP Letter. ACP Letters are short research articles that report particularly important results and major advances in a concise and engaging style. Such articles include one or more of the following characteristic features:

  • Important discoveries and research highlights in atmospheric chemistry and physics.
  • Solutions to or progress with long-standing and important questions in atmospheric research.
  • Research findings of high interest to the broad geoscience community or to the broader public and media.

In this first ACP Letter the authors describe that the amount of energy reflected back into space because of man-made particles is highly uncertain. Processes related to naturally occurring particles cause most of the uncertainty, but these processes are poorly constrained by present-day measurements. The authors show that measurements over the Southern Ocean, far from pollution sources, efficiently reduce climate model uncertainties. The results pave the way to designing experiments and measurement campaigns that reduce this uncertainty even further.
