LCDC: low cloud cover, MCDC: mid-level cloud cover, HCDC: high-level cloud cover. Correlation coefficients (r) represent ocean, land, and total domain averages, the standard error (SD), number of significant p-values, and the order of magnitude of the minimum p-value for field significance testing. Walker’s test for global field significance requires a minimum p-value to be no greater than 10−7.
