Sea Ice Concentration

Daily Arctic sea ice concentration (SIC) products at NL EASE grid (25km x 25km) obtained from SMOS Level 1B products provided by ESA (v6.20) using a new methodological approach based on the Maximum-likelihood estimation. The algorithm is described in the paper ‘New methodology to estimate Arctic sea ice concentration from SMOS combining brightness temperature differences in a maximum-likelihood estimator’, Gabarro, C., Turiel, A.,Elosegui, P., Pla-Resina, J. A., Portabella, M., The Cryosphere, 11: 4, 1987-2002, 2017, DOI: 10.5194/tc-11-1987-2017.
