The system is being developed in collaboration with the Norwegian Meteorological Institute and M\u00e9t\u00e9o-France. It is based on the M\u00e9t\u00e9o-France SURFEX land surface model, and uses various variants of the Ensemble Kalman filter and Particle filer method. It also uses the Extended Kalman filter method from M\u00e9t\u00e9o-France. The system assimilates land surface temperature and soil moisture; it will be extended to snow variables later. Observations assimilated are from in situ platforms; later, observations from satellite platforms will be assimilated. The main objective for developing this assimilation system is to evaluate observations and models; analyses of land surface variables will be produced. Results will benefit Numerical Weather Prediction agencies, space agencies and the broad scientific community.<\/p>\n","protected":false},"template":"","meta":{"_acf_changed":false,"_searchwp_excluded":"","_id":"","_status":"PUBLISHED","_sync_date":"2026-09-11 15:02:57","footnotes":""},"nva_tax_category":[1095],"class_list":["post-120360","nva_publication","type-nva_publication","status-publish","hentry","nva_tax_category-report"],"acf":[],"_links":{"self":[{"href":"https:\/\/nilu.gnist.dev\/en\/wp-json\/wp\/v2\/nva_publication\/120360","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/nilu.gnist.dev\/en\/wp-json\/wp\/v2\/nva_publication"}],"about":[{"href":"https:\/\/nilu.gnist.dev\/en\/wp-json\/wp\/v2\/types\/nva_publication"}],"version-history":[{"count":0,"href":"https:\/\/nilu.gnist.dev\/en\/wp-json\/wp\/v2\/nva_publication\/120360\/revisions"}],"wp:attachment":[{"href":"https:\/\/nilu.gnist.dev\/en\/wp-json\/wp\/v2\/media?parent=120360"}],"wp:term":[{"taxonomy":"nva_tax_category","embeddable":true,"href":"https:\/\/nilu.gnist.dev\/en\/wp-json\/wp\/v2\/nva_tax_category?post=120360"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
