Structure of forecast error covariance in coupled atmosphere–chemistry data assimilation by S. K. Park, S. Lim, M. Zupanski

“…Given the realistic structure of ensemble forecast error covariance produced by the WRF-Chem, we anticipate that the ensemble-based coupled atmosphere–chemistry data assimilation will respond similarly to assimilation of real observations.…”

Quantifying the model structural error in carbon cycle data assimilation systems by S. Kuppel, F. Chevallier, P. Peylin

“…This study explores the impact of the structural error of biosphere models when assimilating net ecosystem exchange (NEE) measurements or CO&lt;sub&gt;2&lt;/sub&gt; concentration measurements to optimise uncertain model parameters within carbon cycle data assimilation systems (CCDASs). This error has been proven difficult to identify and is often neglected in the total uncertainty budget. …”
