The map is showing all possible MODIS sectors into IASCLIP domain. Cloud Difference was calculated from monthly
means, showing as a percentage which areas have more/less cloudiness in certain months (blue/red). For example, taking the
Terra+Aqua (morning+afternoon) average for July and June, it was calculated the difference July-June. The blue
areas show more cloudiness in July and red areas show more cloudiness in June.
