Abstract :
The ice breakup date estimation method using satellite thermal infrared data was developed, and the ice breakup dates on 18 Eurasian lakes for 3 years were estimated by MODIS data in previous studies. In this study, the ice breakup dates on Lake Khanka since 1984 were estimated using AVHRR data, then the relationships between ice breakup dates and local air temperature were evaluated. It shows that a day change of the ice breakup date represents 0.3degC changes of the air temperature in the previous month of the ice breakup dates. The relationship is agreed with that derived from spatial distribution data of the ice breakup dates on 18 Eurasian lakes
