+Use of aviso to trigger job scripts on the European Weather Cloud (EWC)
+=======================================================================
+
+
+* The aviso service runs automatically on EWC machines with the data setup
+  It can be activated and deactivated by the command
+    sudo systemctl start aviso.service
+    sudo systemctl stop aviso.service
+  The status can be viewd be
+    sudo systemctl status aviso.service
+
+* For test purposes it my be used to test the behaviour on past trigger
+  events for a given (past) time range. This can be done by the listen
+  command within an env, where aviso is installed, like
+    sudo systemctl stop aviso.service
+    mamba activate avisoenv
+    aviso listen --from 2025-03-05T00:00:00.0Z --to 2025-03-05T08:00:00.0Z
+  
+* The file config.yaml in the direactory $HOME/.aviso guides the triggering
+
+* if multiple steps are given in a trigger command, like
+   step: [36,72,144]
+  the programs called by the trigger are executed sequentially, possibly
+  not in the time order of the triggers
+
+* the script get_ecmwf_aviso.sh creates ECMWF grib files and converts
+  them to MSS-convorm NetCDF files. One can speed up the process by
+  parallel download the grib files using "DOWNLOAD_ONLY=yes" in the file
+  settings.config and starting convert_all.sh separately.
