Minor data assimilation issues (issues when some data was not properly assimilated)
Observational data is the backbone information source of a reanalysis system. However, during the course of reanalysis, for various technical reasons, some of the data streams got left out. In many cases this is only discovered after the reanalysis has been run. It can also occur that instances in which some radiance data, that should have been blacklisted, are used. Whenever it is possible and the impact is judged to be of significance, the affected periods have been rerun. However, reruns have not been performed for periods with only minor issues in the observational data streams. This has been decided largely based on experiences from verification and real time monitoring. If the impact has been judged to be relatively insignificant, and not to affect the overall consistence and integrity of CARRA reanalysis, reruns have not been performed.
For completeness, a list of the occurrences of missing observational data and affected periods are listed below.
