Download Forcing
Prerequisites:
- Copernicus: you need to create an account
- Naos: you must create a token in: edit profile > access token > add new token (nb: check all the boxes in “select scopes”). Copy the generated token somewhere, it will no longer be displayed
Launch with https://lab.jumeaux-numeriques.fr
Create a new kernel
Create a kernel with demo@demo.fr user
Connect to https://lab.jumeaux-numeriques.fr with user demo@demo.fr
Open a new terminal and execute the following command lines :
cd work/download-forcing/
source download-forcing-env/bin/activate
pip install -r requirements.txt
python -m ipykernel install --user --name=download-forcing-kernelCreate a kernel with your user
Connect to https://lab.jumeaux-numeriques.fr with your user
Open a new terminal and execute the following command lines :
cd work
NAOS_TOKEN=your_token
git clone https://$NAOS_TOKEN@forge.naos-cluster.tech/gpmb/modeles-telemac/download-forcing.git
cd download-forcing
python -m venv download-forcing-env
source download-forcing-env/bin/activate
pip install -r requirements.txt
python -m ipykernel install --user --name=download-forcing-kernelSelect the kernel
click on "File Browser" :
Open download-forcing.notebook.ipynb
click on "Switch Kernel" :
Select download-forcing-kernel :
Run the simulation
Start execution
-
In the first cell
Credentials:- Copy your NAOS token in
NAOS_TOKEN: str="my token". This token is used to get all the forked projects in NAOS, and to update them with the forcing files generated. - Set
WRITE_IN_NAOStoFalseif you don't want to update the forked projects in NAOS (debug mode).
- Copy your NAOS token in
-
Execute this cell:
- you need to enter your Copernicus user and password
- this will generate the credentials to download the Copernicus datas, and save the credentials in :
home/.copernicusmarine/.copernicusmarine-credentials - Note : this identification must only be done once, it is no longer useful once the credentials have been generated and saved in your workspace
-
Enter your parameters either :
-
in the interface part : "Execute with the interface"
- Choose a study in all forked projects
- Choose the start and end dates
- Click on
Update forcing files
-
or in the command line part : "Execute with a prompt"
- By default, the forked projects used are :
- Set all parameters (2D or/and 3D)
- Choose the start and end dates
- Execute the cell
-
Update the project with the latest version (only for new versions)
git init
git reset --hard HEAD
git pull https://$NAOS_TOKEN@forge.naos-cluster.tech/gpmb/modeles-telemac/download-forcing.gitWith Docker
You can execute the download-forcing.py script easily with the provided docker image:
docker run \
-e COPERNICUS_LOGIN="your_username" \
-e COPERNICUS_PASSWORD="your_password" \
-e START_DATE="2024-05-01T00:00:00.000000Z"
-e END_DATE="2024-05-04T00:00:00.000000Z"
