Abstract :
This paper presents the improvements of an absolute calibration reference system based on simulated TOA BRF time series over bright desert targets. The current work highlights a case study performed over Libya4 demonstrating that it is possible to achieve a mean accuracy of 3% when simulation are compared with calibrated observations. This activity is part of VITO contribution to CEOS/WGCV/IVOS calibration mission.
