GRACE solves for mass change on 3 degree cells called mascons, and that is the real resolution of the data. The 0.5 and 1 degree grids are that same solution drawn more finely. Cells inside one mascon do differ, because the gain factors and the GLDAS terms vary from cell to cell, but every one of those differences comes from a land surface model. No grid here holds a second GRACE measurement.
When enabled, the scale runs to the 95th percentile of |value| over the cells on show and all months, globally or within a region, so a few extreme cells saturate instead of flattening everything else. 0 is always the center color.
