Atmospheric correction of APEX hyperspectral data
Miscellanea Geographica: Regional Studies on Development, 2016 Atmospheric correction plays a crucial role among the processing steps applied to remotely sensed hyperspectral data. Atmospheric correction comprises a group of procedures needed to remove atmospheric effects from observed spectra, i.e.

Neural network for aerosol retrieval from hyperspectral imagery [PDF]
Atmospheric Measurement Techniques, 2019 We retrieve aerosol optical thickness (AOT) independently for brown carbon, dust and sulfate from hyperspectral image data. The model, a neural network, is trained on atmospheric radiative transfer calculations from MODTRAN 6.0 with varying aerosol ...
