| Outline of Final Research Achievements |
From 2012 to 3 winter season of 2014, We carried out several in-situ measurements and the fundamental experiments for characteristics of microwave radiation, reflection and scattering by the snow and sea ice in Saroma-ko lagoon, in the Sea of Okhotsk ocean, and in the campus during 2012-2014 winters. We examined which frequencies and polarization were sensitive to roughness, snow depth, ice thickness, vertical profiles of internal temperature and salinity, and surface melting on sea ice. Then we applied the ice parameters which derived from field observations to satellite-borne microwave sensors, and developed the algorithms that are able to estimate or detect thickness and surface state of sea ice from satellite data. The estimated results were validated by comparing with the in-situ data derived from observations with the icebreakers. With this algorithm, we published experimentally data sets for ice concentration and thickness for the Sea of Okhotsk and the Arctic Ocean.
