Because of significant discrepancies between datasets covering oceans and Antarctica, and the particular difficulties involved in accurately measuring these regions, we have limited our analysis to land-based (non-Antarctic) data. Current oceanic and Antarctic datasets lack the accuracy necessary for the standards of this website.
