Table 2: Gap-fill validation outcomes for six validation scenarios, where 5, 10, 20, 30, 40 and 50% of observed (un-filled) remote-sensed MODIS land surface temperature (LST) data were randomly removed and subsequently gap-filled.

From: High resolution temperature data for ecological research and management on the Southern Ocean Islands
