To further the exploitation of Metop/IASI, we investigate the sensitivity of the spectral radiance measurements to significant aerosol concentrations such as Sahara dust, biomass burning or fresh volcanic aerosol.  We plan to develop an algorithm to retrieve aerosol features from nadir-looking high-spectral resolution spectrometers operating in the thermal infrared.  The algorithm should cover aerosols located in the boundary layer and at higher altitudes in the free troposphere, either above sea or land by taking into account the land surface emissivity.  The algorithm will be tested and evaluated by processing of nadir infrared spectral radiance measurements from former space instruments (e.g. IMG/ADEOS).

The main deliverables to ACCENT will be scientific manuscripts.
