Essential Climate Variables
ACSIS Essential Climate Variables (ECVs) will be chosen to provide a multivariate synthesis of the state of the NA climate system and how it is changing. These may include metrics that characterise Ocean Heat Content, aerosol-cloud interactions, and basin-scale trends in methane. The figure below highlights some potential examples. The ECVs will be updated regularly, and made available through a portal on the project website. In Years 1, 3, and 5 we will produce synthesis reports quantifying the state of the system and recent changes across multiple variables (including the ECVs).
