Ivan Smiljanic (EUMETSAT) - Dust and aerosol detection with MTG-I FCI
Ivan Smiljanic talks about aerosol detection with the new FCI instrument. Higher number of spectral channels coupled with increased spatial resolution make detection of aerosol better than ever.
Drawing from enhanced spectral coverage of the MTG FCI instrument (comparing with MSG SEVIRI), enhanced capabilities of aerosol detection are expected. Major improvements are during daytime related to existence of new channels with shorter wavelengths (namely VIS0.44 and VIS0.55), and to existence of new NIR1.38 that is specifically designed for detection of higher level features (including aerosols). During night time (ie 24h), enhanced spatial and radiometric resolution of IR channels offer better sensitivity to aerosols with larger particles like dust, volcanic ash or even a pollen.
