Using GRACE to Track Ocean Currents

NASA and university scientists developed a new way to use GRACE measurements to track changes in Atlantic Ocean currents. This opens a path to better monitoring and understanding of how ocean circulation is changing and what the changes may mean for future climate. Image: NASA/JPL-Caltech.


NASA's Gravity Recovery and Climate Experiment (GRACE) mission accurately maps variations in Earth's gravity field. GRACE maps Earth's gravity field by making accurate measurements of the distance between the two identical orbiting GRACE satellites using GPS and a microwave ranging system.


The Earth Observing System Data and Information System is a key core capability in NASA’s Earth Science Data Systems Program. It provides end-to-end capabilities for managing NASA’s Earth science data from various sources—satellites, aircraft, field measurements, and various other programs.

Tracking Ocean Currents from Space: A New Application of GRACE Data

A team of NASA and university scientists has developed a new way to use measurements from NASA's GRACE mission to track changes in Atlantic Ocean currents.

Remote Sensing Derived Environmental Indicators for Decision Making

Event Date: November 28, 2016

Join us as we discuss remote sensing derived environmental indicator data sets that can enable environmental decision making. We focus on three major issue areas: ambient air pollution, coastal eutrophication and biomass burning.
