The Nadir reflectances, measured by the SCIAMACHY hyperspectral sensor, are used to retrieve vertical column concentrations of nitrogen dioxide (NO2), resulting from anthropogenic pollution. The estimation process is realized via a blind source separation method: the unmixing of the NO2 spectral waveform from the overall atmospheric absorption contribution within the logarithmic reflectance spectra is realized.

Abstract
The Nadir reflectances, measured by the SCIAMACHY hyperspectral sensor, are used to retrieve vertical column concentrations of nitrogen dioxide (NO2), resulting from anthropogenic pollution. The estimation process is realized via a blind source separation method: the unmixing of the NO2 spectral waveform from the overall atmospheric absorption contribution within the logarithmic reflectance spectra is realized.File in questo prodotto:
