Inversion Analysis of Sea Ice Physical Parameters Through Radiative Transfer Model and Simulated Annealing Method

In this paper, the work done for a modified sea ice inverse scattering model, the Radiative Transfer Inverse Scattering Model with Simulated Annealing (RTISM-SA) is presented. The study utilizes artificially grown saline ice data measured and reported during the CRRELEX'93 experiments to verify the performance of the inverse model. The results for the retrieval of saline ice thickness using both single and multi-polarization radar backscatter data shall be discussed. The results show that retrieval of sea ice thickness using the inverse model is possible and that the use of multi-polarization data improves the accuracy. Next, the model is extended to incorporate multi-parameter retrieval. The latest results show promise in the use of the RTISM-SA to retrieve multiple physical parameters of the sea ice.
