Running CAMS (Tutorial)¶

This tutorial will teach you how to run the CAMS GUI with a simple scenario in simulation mode.

• Table of contents
• Running CAMS (Tutorial)
  • Accessing the files for a simulated cloud environment
  • Scenario setup

First of all, make sure you successfully completed the Installation (Developer) tutorial. Then, open a terminal and change the current directory to the folder where the core packages are installed.

cd /path/to/nephelae_workspace

Accessing the files for a simulated cloud environment¶

In order to run CAMS in fully simulated mode first yout need a mesoNH file describing a synthetic atmospheric environment. MesoNH files are databases in NetCDF (.nc) format.

The computer girofle at LAAS contains a mesoNH file that can be used with CAMS. You can use the command below to mount the folder the remote folder as a local directory:

sshfs girofle.laas.fr:/media/Nephelae-Data/data/Nephelae/ mesonh_girofle_mount/

The recommended file for this tutorial is:

REFHR.1.ARMCu.4D.nc

Despite its huge size (~72 GB), the best way to work with this particular file is to download it to your computer. If you are at LAAS connected with an Ethernet cable, you have a high-bandwith and low-lattency link. Therefore you can read the files in the remote folder directly, but beware of errors that can occur if the quality of the connection degrades.

Scenario setup¶

A valid configuration file is required to run the graphical interface server. Scenario configuration files describe the atmospheric environment and the UAVs so CAMS can use the appropriate algorithms and models to manage them.

For this tutorial a simple

There are dedicated tutorial and reference guide wiki pages for scenario configuration, but for an initial run let's use a simple file.
