Observation assimilated in ERA5

Dear everyone,

Is there a way to know which experimental data are used for assimilation in ERA5 at a specific location and time period ?

In the ERA5 documentation (ERA5: data documentation - Copernicus Knowledge Base - ECMWF Confluence Wiki), there is a list of datasets but not the coordinates and measurement period of each device.

Thank you,

Mathieu Landreau
