Since 2006, we organize workshops for the DIVA users, principally members of the region groups responsible for the climatology production in SeaDataNet. During these workshops, several experts are present to help newcomers and the latest developments are presented for advanced users. Generally, a wish-list from users is established at the end of the workshop and most of the changes are implemented during the following weeks or months.
Previous workshops: information about the previous workshops (including presentations).
Diva Workshop – 2018
This page provides the relevant information about the Diva user workshops organised in the frame of H2020 SeaDataCloud project. Diva and DIVAnd are software tools implementing advanced techniques to generate gridded fields from in situ observations.
General information

Preparation
Participants will have with them a laptop with:
- 16 GB RAM memory and
- sufficient free disk space (approx. 50 GB).
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.
Installation
- Julia language
- IJulia, the Julia kernel for Jupyter.
- OceanDataView, to pre-process the data files.
- Nco, a set of netCDF operators for regridding, editing etc.
More details about the procedure: installation.
