Once in execution this command will create a process waiting for notifications. Users can terminate the application by typing CTRL+C .
Note, the configuration file is only read at start time, therefore every time users make changes to it they need to restart the listening process.

Upgrading AVISO installation

To upgrade Aviso to a newer version once it is available run the following command:

pip3 install --upgrade pyaviso

Aviso configuration file allows the definition of multiple listeners. Alternatively, the listeners configuration can be indicated as an independent file or multiple files:

...

In absence of --to, the system after having retrieved the past notifications, it ​will continue listening to future notifications. If --to is defined Aviso will terminate once retrieved all the past notifications.

Examples

There is a GitHub repository with collection of example Python scripts and listener configuration files specifically designed for the AVISO software and notifications generated by ECMWF. These examples are intended to illustrate how AVISO can be effectively used with data distributed by ECMWF and we strongly recommend going through the examples if you intend to use AVISO to get notifications about availability of ECMWF data.
