    We are happy to announce our new interactive GRACE Data Analysis Tool. You can now interactively visualize GRACE Level-3 data, including hydrology basin averages, and users can download the corresponding time series. This tool will expand over time - please let us know what additional features and functionalities would help you in your analysis and applications of GRACE and GRACE Follow-On data! less

    GRACE: RL06 reprocessing completed

    The GRACE Project's data centers (JPL, CSR, GFZ) have released the first batch of reprocessed RL06 Level-2 data (spanning 04/2002 through 08/2016). The corresponding grids of Level-3 data (terrestr... more
    The GRACE Project's data centers (JPL, CSR, GFZ) have released the first batch of reprocessed RL06 Level-2 data (spanning 04/2002 through 08/2016). The corresponding grids of Level-3 data (terrestrial water storage, ocean bottom pressure), as well as ancillary files (e.g., geocenter, GIA) are currently being assessed and will be released by the end of August, 2018. less

    While the GRACE satellites delivered their last (as in: final!) ranging data for gravity field processing in June 2017, the science data system has not been idle. JPL, CSR and GFZ are actively working on reprocessing the entire GRACE data set (04/2002 - 06/2017) with revised data editing and parameterization, updated AOD1B background models, reprocessed Level-1B (KBR & SCA) data, updated tide models, and other improvements in force models. We expect to finish this reprocessing in Spring 2018. In addition to RL06, the processing teams continue to evaluate and improve the so-called 'ACC transplant' data months of 2017, when only a single accelerometer was available. While this patch enabled us to process gravity fields, the noise levels are currently noticeably higher than during nominal months. With some additional analysis, we are cautiously optimistic that we can improve upon this lower S/N ratio - stay tuned for updates! less

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.
