The OPTIMA project: data simulation and correction procedures for PRISMA mission products

OPTIMA (“Advanced methods for the analysis, integration and optimization of PRISMA mission level 1 and 2 products†) is one of the five independent scientific research projects funded by the Italian Space Agency to study the applications and performances of the imaging spectrometer and the panchromatic camera of the PRISMA mission. One of the main tasks of the project is the implementation of advanced autonomous techniques for radiometric calibration and atmospheric corrections. Besides, in the framework of the project, a sensor data simulator has been developed to test data processing algorithms. In this paper we discuss the optimized destriping procedure and the autonomous algorithm developed for the correction of the atmospheric effects. The developed procedures provides refined at sensor radiance and at-ground spectral reflectance images. Results from simulated images are presented and discussed.
