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.
DIVAnd are software tools implementing advanced techniques to generate gridded fields from in situ observations.
Participants are expected to be partners of SeaDataCloud or EMODnet Chemistry or Biology lots. Other scientists or data managers may request an invitation by contacting the organisers.
Priority will be given to those partners responsible for the Product preparation.
The registration is done by email: contact C. Troupin with copy to A. Barth.
Deadline: 31st of January, 2018.
From Tuesday 3 April (1.30 PM) to Friday 6 April (3 PM), 2018.
Participants are invited to consult the following list.
The workshop will be focused on
DIVAnd (n-dimensional interpolation), unlike the previous editions, which were dedicated to the 2D version (DIVA). A specific session will be dedicated to the 3rd SeaDataCloud Product Meeting on Friday afternoon.
Meeting pointing: side entrance (place Cockerill) at 1.15 PM.
Lectures start at 1.30 PM
What is a jupyter-notebook?
Basic Julia commands and major differences with MATLAB and Python
Introduction to variational analysis
+ Demo CINECA jupyterhub
Preparation of topography
How to run
DIVAnd (common dataset) using prepared notebooks and sample data
Configuration for regional products
Discussion: priorities of features from
DIVA implemented in new version
Generation of regional products and optimisation
Afternoon (finish at 3PM), parallel session:
SeaDataCloud Product Meeting
Question and answers and advanced topics (advection, reference fields, …)
Meeting closure: 3 PM.
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.
- 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.
Before the workshop…
If you plan to use your own dataset, please verify that it has been quality controlled.
Bring power adapters if needed (https://www.power-plugs-sockets.com/belgium/).
