The aim of the project was to identify atmospheric visibility change predictors on a hourly time scale, among multi-sensor observation data sets, including ground-based instruments and satellites. The project involved the collaboration of CNRS and HYGEOS.

Animations are proposed for several situations:
Predictors
Six predictors were selected [Elias et al., 2017], from several parameters which can be observed operationally in an airport:
We also conducted a study on the impact of the hydrated aerosols composing the mist: they can have a significant impact in radiative transfer in the fog as they contribute by ~20% in the visibility drop at the fog formation [Elias et al., 2009]; [Elias et al., 2015].
