El Niño and La Niña Seen from Space: How the Planet’s Temperature Pattern Shifts During ENSO Events
El Niño and La Niña are often described with a single number: the temperature anomaly in the tropical Pacific. That number is useful, but it hides the most interesting part of the story. ENSO is not only a warming or cooling of one ocean region. It is a global reorganization of heat, clouds, circulation and […]

Cloud radiative effect shows net cooling
This project creates an interactive 3D visualization of NASA CERES EBAF climate data. The goal is to make the spatial pattern of cloud radiative effects easier to explore than in a static map. Instead of showing the data as a flat world projection, the code converts the gridded CERES dataset into a rotatable, zoomable globe. […]
