    No RL05 Level-2 products could be generated and delivered for May 2015 due to planned switch-offs of the GRACE-A and GRACE-B Microwave Assemblies (MWA) and Instrument Control Units (ICU) in order to reduce the load on the batteries (see also section Level-1 Data Processing). Level-3 gridded TWS/OBP fields will be available again for 06/2015. less

Top Data Sets

  • GRACE Tellus LAND Grids

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

    The data browser 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 Tellus OCEAN Grids

    Ocean bottom pressure from GRACE is updated monthly, and is provided on 1-degree global grids.

GRACE Follow-On

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.

  • 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.

  • Total water storage from GRACE, 2007

    This image shows the mean annual amplitude of total water storage on Earth in 2007 as measured by GRACE.
