A STUDY ON EXTRACTING THIN SEA ICE AREA FROM SPACE
Global warming is one of the most serious problems the earth is facing in the 21 st Century. In order to detect the sign of global warming, the importance of sea ice monitoring is increasing. Especially, sea ice thickness is an key parameter for understanding the heat flux of sea ice area. However,...

The correlation between RSI data and MODIS data(IFOV = 250 m) was also examined for the thin ice area. The result also suggested the possibility of extracting thin sea ice area from MODIS data. Based on these results, the authors have examined possibility of extracting thin sea ice area with passive microwave sensor AMSR-E by using thin ice area estimated with MODIS data as truth data. Since the horizontal polarization of 19 GHz are more sensitive to water than the vertical polarization of 19 GHz, the authors have utilized the polarization difference of 19 GHz for extracting thin sea ice area from AMSR-E data. The detailed study result will be presented in this paper.

In this study authors have examined the possibility of extracting thin sea ice area from remotely sensed data from space. The study was performed in the Sea of Okhotsk.
