The bias problem with climate satellites

TL;DR

The European Space Agency's Sentinel 3B satellite collects data on essential climate variables to monitor Earth's climate and contribute to existing climate datasets, but the data must go through a rigorous verification process to remove biases before being added to the datasets.
