Earth observation is an essential tool for improving our understanding of the remote and inaccessible polar regions. The acquisition of high-quality satellite data-sets is vital to observing and understanding environmental change in Antarctica.

The SCAR Earth Observation Action Group (EOAG) aims to be a permanent advocate for the acquisition of all types of satellite data over the Antarctic and Southern Ocean region (up to 60° S) from multiple space agencies, recommending the type of satellite observations needed to measure Essential Climate Variables (ECV’s) relevant to the Polar regions, and recommending how best to preserve the long term continuity of satellite Earth Observation data records.

EOAG incorporates the former Remote Sensing Action Group.
