How to read aeolus mie wind with harp

By reading the HARP’s instructions, I now have a question about how to read the MIE wind in the satellite data

You can use the ingestion options argument for this.
For instance:

harp.import_product(<your aeolus product>, options="data=mie")

See also the documentation.

Thank you very much for your help, now I want to extract the specific values such as the start time, hlos_wind_velocity and other specific values, how should I do this
