The GRACE\u2010FO satellites carry onboard a novel technology demonstration instrument for intersatellite ranging, the Laser Ranging Interferometer (LRI), in addition to the microwave interferometer (MWI) carried on GRACE. The LRI has out\u2010performed its in\u2010orbit performance requirements both in terms of accuracy as well as the duration of tracking. Here, we compare and validate LRI\u2010based gravity solutions for January 2019 to September 2020 against the MWI solutions. The comparison between the two sets of gravity solutions shows great similarities in general and nearly perfect consistency at a large hydrologic basin spatial scale (100,000\u00a0km\n                    <jats:sup>2<\/jats:sup>\n                    and above), commonly viewed as the spatial resolution established by GRACE. The comparison in the spectral domain shows differences at the higher degrees of the spectrum, with lower error in the zonal and near zonal terms for the LRI solutions. We conclude that the LRI observations can be used to recover time\u2010varying gravity signals to at least the level of accuracy established by the MWI\u2010based solutions. This is a promising finding, especially when considering the benefits of using the LRI over the MWI, such as the great stability of the instrument and the low occurrence of instrument reboot events.\n                  <\/jats:p>","DOI":"10.1029\/2021jb022392","type":"journal-article","created":{"date-parts":[[2021,11,12]],"date-time":"2021-11-12T18:10:11Z","timestamp":1636740611000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":36,"title":["\u201cTime Variable Earth Gravity Field Models From the First Spaceborne Laser Ranging Interferometer\""],"prefix":"10.1029","volume":"126","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9163-7856","authenticated-orcid":false,"given":"N.","family":"Pie","sequence":"first","affiliation":[{"name":"Center for Space Research (CSR) The University of Texas at Austin  Austin TX USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3885-2228","authenticated-orcid":false,"given":"S.
