Corrected indexing problems in downsample_mask that would cause masked reduced-resolution diagnostics to work improperly when the model is in symmetric memory mode or when global indexing is used. This involves passing the starting index in memory of the native-grid field being downsampled in all calls to downsample_mask. In global-indexing mode, this change avoids a series of segmentation faults that stopped the model runs when compiled for debugging. All solutions are bitwise identical in all cases but some down-scaled diagnostics will change in some memory modes, hopefully becoming consistent across all memory modes (although this has yet to be tested in all modes).
