GRACE Follow-On: Science Results, Mission Status and Plans
Abstract
The Gravity Recovery and Climate Experiment Follow-On (GRACE-FO) mission has collected more than three years of monthly gravity and mass change observations since its launch in May 2018. The combined GRACE/GRACE-FO mass change data record is spanning nearly two decades, and is an essential tool to quantify and track Earths water movement and surface mass changes across the planet. Monitoring changes in ice sheets and glaciers, near-surface and underground water storage, the amount of water in large lakes and rivers, as well as changes in sea level and ocean currents provides an integrated global view of how Earths water cycle and energy balance are evolving. In this presentation we will update the community on the current GRACE-FO mission status and near-term plans, including a summary of the instrument and flight system performance (i.e., satellite health status and outlook, performance of precise inter-satellite ranging from the K/Ka band and Laser Ranging Interferometers, and accelerometry as processed at Jet Propulsion Laboratory (JPL), the official Level-1 data analysis center). We will discuss the GRACE-FO science data quality, reprocessing plans, and highlight recent science results, discoveries, and applications.
