It is stated:
WRFDA has an option for dual-resolution hybrid data assimilation, where a high-resolution background can make use of a lower-resolution ensemble for extracting the flow-dependent contribution to the background error. The lower-resolution ensemble should be the parent domain of the higher-resolution child domain that the analysis is performed on.
and the referenced publication indicates the mandatory high resolution background error.
question remains: how to I input this high resolution static background error? There is specific naming convention or an entry in the namelist.input? or ????
Also what is missing in the user manual is some guidance on the quality and completeness of this high resolution static background as this could be a computational driving element.
