Register for High-Latitude Marine Cloud Workshop

Published: 23 August 2021

In March 2018, the Aurora Australis supply vessel heads toward Macquarie Island, the location of the Macquarie Island Cloud and Radiation Experiment (MICRE). The supply vessel carried ARM instruments as part of the Measurements of Aerosols, Radiation, and Clouds over the Southern Ocean (MARCUS) field campaign.

A user-driven workshop will focus on observations and modeling of high-latitude cold-sector marine clouds, especially as related to recent field campaigns in the Southern Ocean and Norway, as well as related campaigns or long-term sites (e.g., Eastern North Atlantic, North Slope of Alaska).

The Zoom-based workshop will take place from 1 to 4 p.m. Eastern time on September 7 and 8.

This workshop was recommended at the close of a breakout session on high-latitude marine clouds during the 2021 Joint Atmospheric Radiation Measurement (ARM) User Facility/Atmospheric System Research (ASR) Principal Investigators (PI) Meeting. The breakout session highlighted the importance of high-latitude marine clouds in the climate system, as well as uncertainties in cloud feedbacks in a warming climate, as related to aerosol-cloud-precipitation processes.

The purpose of this workshop is to foster further interactions and lay the groundwork for observation-driven modeling exercises/evaluations to be developed for community participation.

The proposed list of presenters and moderators includes the PIs for three recent high-latitude ARM campaigns:

Those interested in attending the workshop should email Mandi Campbell (, who will provide updates and a Zoom link for the meeting.
