The GARRLiC algorithm provides micro-physical and optical aerosol properties, inverting simultaneously sun/sky radiometer and lidar ground-based observations. This synergistic approach can provide column-integrated parameters, like the particle volume size distribution, the complex refractive indexes, the spherical fraction, the Aerosol Optical Depth and absorption, the single scattering albedo. The LIDAR vertically resolved measurement allows to retrieve […]
Presentation GIRAFE is a software which provides forecasts of plumes trajectories. Trajectories are calculated using lagrangian dispertion model FLEXPART and ECMWF meteorological fields. GIRAFE uses fire detections of MODIS satellite in order to predict plumes trajectories, or MACC satellite data. At the moment two versions of GIRAFE exists : GIRAFE-MODIS : MODIS (Moderate Resolution Imaging […]
BAMED (Balloons over the Mediterranean sea) is a model providing trajectory forecasts for BPLB (Boundary Layer Pressurized Balloons) over the Mediterranean sea. During campaigns it can be routinely computed using the meteorological fields given by the operational ECMWF 10-day weather forecast.

The project The MIMOSA model (Modélisation Isentrope du transport Méso-échelle de l’Ozone Stratosphérique par Advection) has been developed at Service d’Aéronomie in the frame of the European Union project METRO (MEridional TRansport of Ozone in the lower stratosphere) which was part of THESEO (Third European Stratospheric Experiment on Ozone) 2000 campaigns. A full description of […]
The 4A/OP software package is the operational version of the fast and accurate radiative transfer model 4A (Automatized Atmospheric Absorption Atlas), developed, maintained and validated at LMD. The 4A high spectral resolution line-by-line radiative transfer model (Scott and Chédin, 1981) pioneered the idea of bypassing the time-consuming line-by-line process by calculating once and for all […]
The project REPROBUS (Reactive Processes Ruling the Ozone Budget in the Stratosphere) is a Chemical Transport Model that describes the stratospheric chemistry by means of 55 chemical species and 147 chemical reactions. Heterogeneous chemistry on Polar Stratospheric Clouds and liquid aerosol is also implemented in the model REPROBUS wind and temperature fields are forced every […]
SOFT-IO (Sauvage et al., 2017) is a tool based on the FLEXPART particle dispersion model (Stohl et al., 2005) coupled on emission inventories provided in the scientific community (e.g. GVAS v1.2, GFED4, MACCity, EDGAR). It has been developed to quantify source/receptor links for atmospheric trace gases considered as passive, such as carbon monoxide (CO), and […]
