Monitoring of NRT Products: Desroziers plots
This page displays monthly RO Desroziers observation uncertainty estimates provided by MetOffice and ECMWF. Plots and data can also be downloaded from next demonstration products: Desroziers (MetOffice) and RO error stats (ECMWF). Click on the plot for a more detailed description.
Note that the Desroziers diagnostics are a consistency check on the input covariances provided to the data assimilation. They can be used to provide updated estimates of observation-, background- and analysis-error covariance matrices. However, these estimates depend upon the matrices which are provided as input, so should be carefully considered before being used.
