Characterizing the Space Between Clouds and Clear Sky

by Susan Trumbore 7 February 20257 February 2025

The area near clouds is often classified as ‘clear sky’, but a new study demonstrates the potential biases of misclassifying these transition zones and their significance for Earth’s energy budget.
