Contenu du module

Basis on aerosol chemical composition, microphysical (size distribution, shape), optical and radiative properties, sources and formation processes.

Basis on radiation-matter interactions (scattering/polarization/absorption/emission) and radiative transfer in the atmosphere (single and multiple scattering).

State of the art of ground-based and satellite remote sensing sensors dedicated to aerosol and gas characterization (optical, microphysical and chemical column integrated properties). Passive systems (sun/sky-photometer, polarimeter, spectrometer, infrared radiometer, …) mostly providing column integrated properties and active system elastic backscatter, Raman lidar, …, providing vertical distribution of aerosol/gas properties. Available aerosol/gas properties versus instrumental characteristics.

State of the art for in situ instrumentations (online analyzers for gaseous precursors (NOx, SO2, GC-MS, PTR-MS), mass concentration analyzers and particle counters (SMPS, CPC, TEOM FDMS, beta gauges), chemical composition analyzers (aethalometers, aerosol mass spectrometers (AMS, ACSM, ATOFMS), semi-continuous analyzers (PILS, MARGA).

Basis on inverse methods (introduction to forward and inverse problems, from simple to advanced approaches) Instrumental synergies. Field/Labs. Simple experiments and data analysis form available instruments operating with CaPPA consortium (sun-photometer, elastic backscatter and Raman Lidars, Wind Lidar. Links with in situ observations.

Presentation of the main atmospheric networks (AERONET, GALION, EARLINET, EMEP, MERA) dedicated aerosol/gas monitoring (instrument, calibration, data quality, data transfer, data processing, aerosol parameters) and current National and European observating systems (ACTRIS, ORAURE, …).

Presentation of specific field campaigns in different environments and at different scales. Tools for analysis (CMB, PMF models, in relation with gaseous pollutants and atmospheric dynamics), backtrajectories.
