Outline of Final Research Achievements |
The final goal of this research is to evaluate an effect of climate change into Arctic land area. In this research, we investigated a method to monitor freezing and thawing of tundra lakes (thermokarst lakes) in Arctic region by using C-band and L-band synthetic aperture radar (SAR) data. And then, we evaluated the effect of climate change into Arctic land area. We investigated the time series of C-band and L-band backscattering coefficients of tundra lakes located in northern Alaska by using the SAR data archived during more than 20 years. The effect of climate change was evaluated by extracting the ice growing speed and the freezing /thawing time changes. We also investigated the possibilities of currently available SAR data for the use of this research.
