Sea Surface Temperature Anomaly

These maps depict how much hotter or cooler an ocean basin was compared to the long-term average. Temperature anomalies can indicate changes in ocean circulation or the arrival of patterns like El Niño and La Niña.

Earth at Night

Satellite images of Earth at night have been a curiosity for the public and a tool of fundamental research for at least 25 years. They have provided a broad, beautiful picture, showing how humans have shaped the planet and lit up the darkness.

Total Rainfall

These maps depict monthly total rainfall around the world. Rainfall is the primary source of fresh water for humans, plants, and animals. Rain also moves heat between the atmosphere, oceans, and land.

Snow Cover

Snow and ice influence climate by reflecting sunlight back into space. When it melts, snow is a source of water for drinking and vegetation; too much snowmelt can lead to floods. These maps show average snow cover by month.
