This presentation deck outlines the CMIP6 output request presented at ACME All-Hands meeting in June 2017. It includes detailed information on various atmosphere and land fields that are both part of and not part of the ACME output, covering parameters like radiation, moisture, carbon flux, and vegetation cover.
