We are in the process of migrating all NASA Earth science data sites into Earthdata from now until end of 2026. Not all NASA Earth science data and resources will appear here until then. Thank you for your patience as we make this transition. Read about the Web Unification Project

Featured Water Quality Observation Method: PACE

NASA's Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) platform measures the distribution of phytoplankton, a key indicator of ocean health. Aboard PACE is the Ocean Color Instrument (OCI), a highly advanced optical spectrometer used to measure substances or particles present in seawater such as chlorophyll, a green pigment found in most phytoplankton species. Monitoring global chlorophyll and phytoplankton distribution and abundance help us better understand water quality and the complex systems that drive ocean ecology.

This is an image showing simulated chlorophyll concentrations in the ocean on March 21, 2022. The image has a black background. Regions colored in blue represent areas of low chlorophyll concentration, green are medium, and red areas have high levels. The image has strips of black running through the colored areas from the upper left to the lower right to show PACE’s orbital track around the globe and places across the ocean where it has not scanned.

Preparing for PACE Data

Simulated data help Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) users prepare a day in the life of the new satellite.

This rectangular image shows phytoplankton levels along Florida and the East Coast of the United States, the Bahamas, and Cuba. Land is colored in muted shades of brown and green, water is dark blue, and snow is white. Nearshore are bands of light to dark green depicting picoeukaryote organism levels. Further out to sea are regions in variations of light blue showing the presences of prochlorococcus cyanobacteria.

New PACE Data Tutorials

A series of Jupyter notebook tutorials show how to retrieve and use data from NASA's Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) mission.
