Paper Abstract

This paper presents an analysis of the main artifacts introduced by the non- uniformity of the instrumental characteristics in an image dataset simulated by taking into account the main technical features of the FLORIS sensor. The dataset was produced by using a hyperspectral image simulation tool – named FLISM (Fluorescence Image Simulator for space Missions) – specifically implemented to produce images of fluorescent and non-fluorescent targets acquired by a pushbroom hyperspectral instrument. In this specific case, the available technical specifications of the FLORIS sensor were taken into account to investigate some critical issues concerning Solar Induced Fluorescence (SIF) retrieval in vegetated areas by means of the FLD (Fraunhofer Line Discriminator) method, which relies on the telluric O2-A and O2-B lines to decouple the weak SIF signal of vegetation from the backscattered radiance.
