Global mapping of ice thickness distribution in the seasonal ice zone and its application to the numerical sea ice model

为了开发一种从卫星估算季节性海冰带冰厚度分布的算法，在鄂霍次克海南部和林肯海进行了验证测量。结果表明，L波段合成孔径雷达(PALSAR)在这方面是有用的。基于PALSAR得到的海冰厚度分布以及AMSR得到的冰的漂移模式和浓度，验证了长期用于数值海冰模式的Hibler的冰流变学。

To develop an algorism for estimating the ice thickness distribution in the seasonal sea ice zone from satellite, the validation measurement was conducted in the southern Sea of Okhotsk and the Lincoln Sea. It is shown that PALSAR (L-band SAR) is useful for this purpose. Based on the PALSAR-derived ice thickness distribution along with the AMSR-derived ice drift pattern and concentration, the ice rheology by Hibler which has long been used in the numerical sea ice model was also validated.
