To better constrain the uncertainty in recent firn thickness changes, we develop an ensemble of 54 model scenarios of firn evolution between 1992 and 2017. Using statistical emulation of firn-densification models, we quantify the impact of firn compaction formulation, differing climatic forcing, and surface snow density on firn thickness evolution. At basin scales, the ensemble uncertainty in firn thickness change ranges between 0.2 and 1.0&nbsp;cm yr<sup>−1</sup> (15%–300% relative uncertainty), with the choice of climate forcing having the largest influence on the spread. Our results show the regions of the ice sheet where unexplained discrepancies exist between observed elevation changes and an extensive set of modeled firn thickness changes estimates, marking an important step toward more accurately constraining ice sheet mass balance.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Uncertainty in East Antarctic firn thickness constrained using a model ensemble approach","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-21 01:33:11.302395","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2021,"MonPub":null,"DateUpdate":"2022-07-25","DateCreate":"2022-07-25","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000641974600074","VABBcode":null,"OpenAcc":1,"DOI":"10.1029/2020GL092060"},"refs":null,"anarec":{"AnaID":354012,"PubliDate":2021,"Pagination":"e2020GL092060","XtraPublOfAnaID":null,"ISBN":null,"Volume":"48","Issue":"7","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42920,"SerRR":"Geophysical Research Letters.
