We present the status of the low degree gravity coefficients C20 and C30 derived from satellite laser ranging and distributed as Technical Note 14. This includes comparisons to independent solutions, and analysis of the impacts the recently adopted time variable gravity forward modeling approach and updates to the GRACE-FO Level-2 products. We also present an update of our ongoing efforts to use the SLR-derived global terrestrial water storage anomaly as an independent assessment of the GRACE-FO Level-2 products, including the impacts of the RL06.3 solutions on this metric.
