Aerosol and Cloud Experiments in the Eastern North Atlantic (ACE-ENA)

For better understanding of aerosols and low clouds in the remote marine environment, ACE-ENA paired measurements from ARM’s Eastern North Atlantic atmospheric observatory in the Azores with data from ARM’s now-retired Gulfstream-159 (G-1) research aircraft. After ACE-ENA concluded in February 2018, early data analysis confirmed several key seasonal variations in aerosol and cloud properties.
