ASTER surface water temperature, which is based on the famous Split Window method, and turbidity algorithms, was validated using in situ surface water temperature and in situ turbidity in Lake Shinji and Lake Nakaumi. The study revealed that the ASTER temperature estimated from 5 ASTER/TIR (Thermal Infrared) bands data has a good corretation with in situ surface water temperature from tower data in the lakes. And the DN of ASTER Band 3, after dark pixel subtraction, has a significant correlation with the in situ turbidity.
