A posteriori verification of analysis and assimilation algorithms (presentation, 2001)

2001-06-01T10:04:00Z

Presentation of Wafaa Sadiki, Claude Fischer and GÃ©rald Desroziers during the ALATNET training course on Data Assimilation in Gourdon, 11-22 June 2001. A posteriori diagnostics in a variational scheme : improve the knowledge of the assimilation systems based on variational approach develop a set of diagnostics allowing to validate a posteriori, any analysis algorith estimate the accuracy of the observation and background error statistics, specified in entry of the assimilation system (…)
