Benefit of vertical localization for sea surface temperature assimilation in isopycnal coordinate model
Wang, Yiguo; Counillon, Francois Stephane; Barthelemy, Sebastien Jean-Claude; Barth, Alexander (Journal article; Peer reviewed, 2022-12-15)Sea surface temperature (SST) observations are a critical data set for long-term climate reconstruction. However, their assimilation with an ensemble-based data assimilation method can degrade performance in the ocean ... -
Super-resolution data assimilation
Barthelemy, Sebastien Jean-Claude; Brajard, Julien; Bertino, Laurent; Counillon, Francois Stephane (Journal article; Peer reviewed, 2022)Increasing model resolution can improve the performance of a data assimilation system because it reduces model error, the system can more optimally use high-resolution observations, and with an ensemble data assimilation ...
