GRACE-FO Mission Status
Felix Landerer, Frank Flechtner, Srinivas Bettadpur, Christopher McCullough, Himanshu Save, and Christoph Dahle

We will present a high-level overview of the GRACE Follow-On mission status, science and instrument performance, and future plans. GRACE-FO has now delivered over two years of monthly gravity field and mass changes map since Jun-2018. These unique observations extend the global mass change climate data record to almost two decades, and allow detailed quantification and process studies of ice melt, sea level changes, and land water storage variations.

GRACE and GRACE-FO Level-1 V04 Data Processing Status
Christopher Mccullough, Tamara Bandikova, William Bertiger, Carmen Boening, Sung Byun, Eugene Fahnestock, Christopher Finch, Nate Harvey, Da Kuang, Felix Landerer, Mark Miller, and Meegyeong Paik

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 software version 04. Here we present analysis of the aforementioned GRACE-FO sensor data, as well a preview of an upcoming GRACE reprocessing, and a discussion of measurement performance.

LRI Instrument status talk
Samuel Francis

In this talk, the current status of the LRI instrument will be presented. Topics will include laser frequency stability since launch, current best estimate of the noises in the LRI range spectra, and a look at some high-frequency signals visible in the LRI range measurement.

SDS Level-2/-3 JPL
David Wiese

This talk will provide a status update on Level-2 data processing at JPL.  Included will be an overview of data products currently delivered to the community.  Assessments of data quality and error levels, along with detailed discussions of the solution strategy will be included.  A comparison of LRI and KBR gravity fields will be provided, in addition to a discussion on efforts to combine both data types in the gravity retrieval.  A look towards an RL07 reprocessing of GRACE and GRACE-FO will additionally be provided, along with preliminary results.
