Comparative Analysis of Seasonal Estimates of Sea Ice Concentrations Determined Using the Okean-01, SSM/I, and Radarsat Satellite Data

Abstract

A comparative analysis is made of seasonal differences in estimates of sea ice concentrations in the regions of the Barents, Kara, and Laptev seas and the adjoining Arctic Ocean during the period 1995-1999 using SSM/I, Okean-01, and Radarsat data and applying the NASA Team, linear mixture, and segmentation model classification algorithms. Seasonal differences between estimates of total concentration and concentrations of perennial and year-old ice were determined. Ice concentration estimates based on Radarsat Scan synthetic aperture radar and Okean-01 measurements were higher than SSM/I data.
