Editing GRACE and GRACE-FO (section)

=== Data products ===

CSR, GFZ, and JPL process observations and ancillary data downloaded from GRACE to produce monthly [[geopotential model]]s of Earth.<ref name="PODAAC">{{cite web |title=GRACE PO.DAAC |url=http://podaac.jpl.nasa.gov/GRACE |website=JPL Physical Oceanography and Distributed Active Archive Center |access-date=11 June 2015}}</ref>  These models are distributed as [[spherical harmonics|spherical harmonic]] coefficients with a maximum degree of 60.  Degree 90 products are also available.  These products have a typical latency of 1–2 months.  These geopotential coefficients may be used to compute [[geoid]] height, gravity anomalies, and changes in the distribution of mass on Earth's surface.<ref>{{cite journal |last1=Wahr |first1=John |last2=Molenaar |first2=M. |last3=Bryan |first3=F. |s2cid=140194666 |title=Time variability of the Earth's gravity field: Hydrological and oceanic effects and their possible detection using GRACE |journal=J.
