GRACE and GRACE-FO Level-1 V04 Data Processing Status
,,- NASA Jet Propulsion Laboratory, California Institute of Technology
The Gravity Recovery and Climate Experiment Follow-On (GRACE-FO), launched in May 2018, provides invaluable information about mass change in the Earth system, continuing the legacy of GRACE. Fundamental requirements for successful mass change recovery are precise orbit determination and inter-satellite ranging, determination of the relative clock alignment of the ultra-stable oscillators (USOs), precise attitude determination, and accelerometry. NASA/Caltech Jet Propulsion Laboratory is the official Level-1 data processing and analysis center, and is currently processing using software version 04. Here we present analysis of the aforementioned GRACE-FO sensor data, as well an overview of the current GRACE reprocessing, and a discussion of measurement system performance. The research presented in this abstract has been carried out at the Jet Propulsion Laboratory, California Institute of Technology, under a contract with the National Aeronautics and Space Administration.
