Thursday

Wrap-up with future development ideas:

  • From data integration to DIVAnd: how to harmonize the workflow
  • Use of residuals to discard non-representative data in the climatology
  • Consistency analysis of DIVAnd output with reference products

Afternoon (finish at 3PM), parallel session:
SeaDataCloud Product Meeting
đź•’ Meeting closure: 3 PM.

Preparation

Computers

Participants will have with them a laptop with:

  • 16 GB RAM memory and
  • sufficient free disk space (approx. 50 GB).
  • Data files necessary for the preparation of a climatology.

More resources might be necessary depending on the resolution and size of the studied domain.

You may also need to check the list of acronyms and definitions.

Workshop material

The notebooks are availabe in the folder notebooks in the zip file. Follow the instructions here to download and open the notebook files.
