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, including gravity fields with the updated accelerometer transplant product.  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..  A look towards an RL07 reprocessing of GRACE and GRACE-FO will additionally be provided.  The reprocessing plans to incorporate the estimation of a full noise covariance model of the satellite observations in the gravity estimates.  Preliminary results incorporating this strategy will be shown and discussed.
