PACE

Plankton, Aerosol, Cloud, ocean Ecosystem

active Mission

PACE will help us better understand our ocean and atmosphere by measuring key variables associated with cloud formation, particles and pollutants in the air, and microscopic, floating marine life (phytoplankton). These observations will help us better monitor ocean health, air quality, and climate change.

PACE and Climate Change

Launched February 2024, NASA’s newest Earth-observing satellite, called PACE (Plankton, Aerosol, Cloud, ocean Ecosystem), will help us better understand how climate change is affecting blooms of ocean phytoplankton. PACE will also help decipher how particles in the air (like dust and smoke) can influence cloud formation and the warming and cooling of the planet.

An aerial view of a portion of the planet shows white, wispy cloud coverage over both land and ocean. Clouds are seen in the bottom left corner extending up towards the top left corner but dwindling as it rises. Clouds are also seen in the top right corner. A green colored land mass is seen along the bottom third of the image. There are some islands off the coast of the land as well. In the dark blue ocean, are vibrant swirls of teal and green phytoplankton blooms.

During the spring and summer in the Barents Sea, north of Norway and Russia, blue and green blooms of phytoplankton are often visible. The Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA’s Aqua satellite captured this true-color image on July 15, 2021.
