General Activity :
Atmospheric optics aims at modelling the propagation through the atmosphere of
the visible light received from the Sun and of the infrared light emited by
the terrestrial surfaces and the atmosphere. Studies conducted at LOA in this
context are addressed to the global climate problem.
A first objective is to quantify the impact of visible and infrared
radiation on the different planetary energetic exchanges
and more specifically to quantify the influence
of clouds on the Earth radiative budget.
The second objective relates to the characterization at the globe scale of
different parameters directly related to the climate evolution
(clouds, aerosols, surfaces) mainly using satellite observations.
The studies conducted in this context aim at:
- Conception of softwares for simulating the radiative transfer, based on
modeling of the earth-atmosphere system.
- Analysis of satellite sensor observations, mainly using satellite picture
processings, and new satellite experiment designing,
- Intensive observations during field campaigns using
at LOA, at ground level or from aircraft or stratospheric balloons, to validate
models or to monitor atmospheric processes.
