Variable List

This page lists the variables that will be included in the NA-CORDEX archive, in rough priority order.
Essential variables will definitely be included.
High Priority variables will be included if at all possible.
Aspirational variables will be included if time and resources allow.

Information about units, sign convention, and whether a variable is instantaneous or time-averaged can be found here. Other variables not on this list (e.g., 3-D variables) may be available from the CORDEX archive on ESGF or directly from the modelers; inquire with the point of contact for each simulation for more information.
