A very important aspect of atmospheric observations is the collaboration between different sensors. Various simultaneous measurements can be used either to validate the acquired data or to provide us with a more detailed understanding of atmospheric processes. We had the opportunity to experience this first hand on a night visit at the Candillargues measurement site.

To begin with, a radiosonde balloon equiped with multiple sensors was launched. Its route in the atmosphere is monitored by a ground station and the acquired data can be used as an input for prediction models.

At the same time, two lidars were operating while an aircraft was flying over the site so that their measurements can be validated against the onboard equipment on the plane. For this process, it is essential that the sky is clear so that the lidar can operate without obstruction.
