| Outline of Final Research Achievements |
The objective of this research is to develop a remotely salinity measurement system for closed waters by mounting a spectral radiometer on autonomous flight UAV that can acquire data with good wavelength resolution automatically from low airspace. In order to achieve this objective, the spectral reflectance / water quality data set at nine times was collected on site at Lake Togo in a closed watershed as a test site for two years. Using that data set, the relationship between reflectance ratio and CDOM (negatively correlated with salinity) in Lake Togo was studied. As a result, spectral reflectance ratio of wavelength optimum for remotely salinity estimation was found.
