Between 2002 and 2016, the Gravity Recovery and Climate Experiment (GRACE) tracked the movement of freshwater around the planet. After more than 15 productive years in orbit, the U.S./German GRACE (Gravity Recovery and Climate Experiment) satellite mission has ended science operations. Training Announcement - Introductory Webinar: Groundwater Monitoring using Observations from NASA’s Gravity Recovery and Climate Experiment (GRACE) Missions This training is offered in English and Spanish. Artist's concept of Gravity Recovery and Climate Experiment GRACE, twin satellites launched in March 2002, are making detailed measurements of Earth's gravity field which will lead to discoveries about gravity and Earth's natural systems. Research based on observations from NASA’s twin NASA/German Aerospace Center’s twin Gravity Recovery and Climate Experiment (GRACE) satellites indicates that between 2002 and 2016, Antarctica shed approximately 125 gigatons of ice per year, causing global sea level to rise by 0.35 millimeters per year. 1.
GRACE 1 and 2 were launched on March 17, 2002. Gravity Recovery And Climate Experiment (GRACE) Mission. Introduction [2] The Gravity Recovery and Climate Experiment (GRACE) is a dedicated satellite mission whose objective is to map the global gravity field with a spatial resolution of 400 km to 40,000 km every thirty days. The mass of the Antarctic ice sheet has changed over the last several years.
When the twin satellites known as the Gravity Recovery and Climate Experiment, or GRACE, were launched in … Monitoring Groundwater Storage Depletion Using Gravity Recovery and Climate Experiment (GRACE) Data in Bakhtegan Catchment, Iran by Nizar Abou Zaki 1,* , Ali Torabi Haghighi 1 , Pekka M. Rossi 1 , Mohammad J. Tourian 2 and Bjørn Kløve 1 Abstract Gravity Recovery and Climate Experiment (GRACE) satellite mission is ground‐breaking information hotspot for the evaluation of groundwater storage. Launched in March 2002, the twin Grace satellites circle the globe using gravity to map changes in Earth's mass 500 kilometers (310 miles) below. The data products specified in this document are obtained from the science instruments and subsystems on board the twin GRACE spacecrafts, and include the results of any ground data processing carried out by the GRACE Science Data System (SDS).
