gcmfaces is a Matlab toolbox designed to analyze results of MITgcm simulations, including ECCOv4 solutions, and to handle gridded earth variables in generic fashion (Forget et al 2015). It allows users to seamlessly deal with various gridding approaches (e.g., all grids distributed via this FTP server) using compact and generic codes as explained in the toolbox documentation. It includes many basic and more evolved functionalities for plotting global maps, computing transports and budgets, etc. as illustrated by gcmfaces_demo.m and the standard analysis (see Forget et al., 2015, 2016).
