Atmospheric optics laboratory

LOA | UMR 8518
Observation and environment, lasers and their applications Research unit Science for a changing planet

Our laboratory studies various components of the atmosphere, mainly clouds, aerosols which are fine particles of anthropic or natural origin (desert dust, biomass fires, marine, urban and volcanic aerosols) and some gases (ozone, water vapor, sulfur dioxide). LOA brings together complementary observational and modeling expertise to determine:
(i) the spatio-temporal distribution of aerosols, clouds and their gaseous precursors
(ii) their micro-physical (size, shape), chemical, hygroscopic, optical and radiative properties
(iii) their impact on the atmosphere and atmospheric radiation. 
With a strong background in atmospheric radiative transfer modeling and measurement inversion methods, our unit has internationally recognized expertise in spaceborne, ground-based and airborne remote sensing. Our expertise covers a wide spectral range, from ultraviolet and solar to thermal infrared and millimeter waves. The laboratory is also involved in the development of measurement instruments, deployed on the ground or onboard aircraft to serve as space prototypes. In addition, the LOA has developed an instrumental platform on the roof of the laboratory that allows for continuous measurement of atmospheric composition using a wide range of ground-based remote sensing instruments and in-situ measurements.
