AB: The Gravity Recovery And Climate Experiment (GRACE) is in the 3rd year of its nominal 5-year operating lifetime. GRACE data have been providing unprecedented insights into the mass distribution and variability evident through measurements of the Earth's gravity field variations. The mean geoid errors have been reduced to less than 1-cm to harmonic degree 70; and monthly variations at 500 km and longer wavelengths are being tracked to 2-mm geoid accuracy. The seasonal and inter-annual variability is being used for applications in hydrology, oceanography, glaciology and geodesy. This presentation presents an overview of the Science applications from GRACE mission. We also review the mission status, including plans for improving the data quality and future data product releases.
