This list of Active Objects appears in Expert Mode and are all the datasets that you currently have open. The last one (IRI MP RESEARCH ATMOSPHERE GLOBAL ECHAM5 biasSST biasSST_hist.D Monthly PressureLevel tmp) is the one you are currently working with.

means the grid is missing
Mmeans the grids match
Omeans the grids are offset
Smeans the grids could match by sampling
Dmeans the grids differ
Grid Comparisons
When you have multiple variables active, a table of grid comparisons appears to the right. These comparisons are between the last variable and all the others (so the last row always has matches or blanks).

As you go from left to right, the datasets listed get more and more specific, ending with the current dependent variable, IRI MP RESEARCH ATMOSPHERE GLOBAL ECHAM5 biasSST biasSST_hist.D Monthly PressureLevel tmp. Datasets with documentation are marked (*): the * links to the documentation directly.

Grids

Grids are the independent variables, i.e. what the current dependent variable (tmp) depends on.
