Top Data Sets

  • JPL Global Land / Ocean Mascons (RL05M_1.v02)

    JPL's global mascons (land water storage & ocean bottom pressure) from GRACE are updated monthly, and are provided on 0.5-degree global grid.
  • GRACE Tellus LAND Grids

    Land water storage from GRACE is updated monthly, and is provided on 1-degree global grids.
  • Interactive Data Browsers

    The data browsers allow the interactive retrieval of GRACE Land data over river basins, as well as the evaluation of long-term trends and mean seasonal amplitudes. Courtesy of U. of Colorado / Boulder.

GRACE Follow-On

Launching in 2017, GRACE Follow-on (GRACE-FO) will continue GRACE's legacy of tracking Earth's water movement to monitor changes in underground water storage, the amount of water stored in large lakes and rivers, soil moisture, ice sheets and glaciers, and sea level caused by the addition of water to the ocean. These discoveries provide a unique view of Earth's climate and have far-reaching benefits to society and the world's population.

  • Scale in the Sky

    The force of gravity not only keeps us from floating away, it also lets NASA study Earth’s water and ice from space. Using a pair of twin satellites named "GRACE," we can monitor our planet’s water.

  • Amazon Basin seasonal hydrology

    These images show the changes in gravity anomalies from GRACE over the Amazon Basin for each month of 2004. 

  • GRACE Sees Groundwater Losses Around the World

    NASA’s Gravity Recovery and Climate Experiment (GRACE) has measured significant groundwater depletion around the world in recent years. These animations show trends in total water storage from Jan. 2003 to Dec. 2009 as measured by GRACE, depicting accumulated groundwater losses over time in Australia, California’s Central Valley and the Middle East, and monthly anomalies in total water storage over the same timeframe in the Indian Subcontinent.
