Measured by satellite rows show the temperature of the ground surface, seen from orbit at the last satellite pass. Sunlit desert ground runs far hotter than the air, and polar ice colder, so these rows are pinned on top and never ranked against weather station air readings.
Readings older than their network allows, and values that fail quality control, are excluded. How we rank.
