<p>This talk will provide a status update on Level-2 data processing at JPL.&#160; Included will be an overview of data products currently delivered to the community, including gravity fields with the updated accelerometer transplant product. &#160;Assessments of data quality and error levels, along with detailed discussions of the solution strategy will be included.&#160; A comparison of LRI and KBR gravity fields will be provided..&#160; A look towards an RL07 reprocessing of GRACE and GRACE-FO will additionally be provided.&#160; The reprocessing plans to incorporate the estimation of a full noise covariance model of the satellite observations in the gravity estimates.&#160; Preliminary results incorporating this strategy will be shown and discussed.</p>
<p>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.</p>
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
