Description

FOR EXPERT USE ONLY. The GRACE-FO Level-1B data provide all necessary inputs to derive monthly time variations in the Earth gravity field. Level-1B data are also used for GRACE orbit and mean gravity field determination. For a detailed description, please see the GRACE-FO Level-1 documentation (https://podaac.jpl.nasa.gov/gravity/gracefo-documentation).
