抄録

An effectiveness of the 8.3 [μm] band in the ASTER/TIR (Advanced Spaceborne Thermal Emission and Reflection radiometer / Thermal Infrared Radiometer) on Sea Surface Temperature (SST) estimation is evaluated together with a re-evaluation of SST estimation accuracy for ASTER/TIR by using MODTRAN 3.7 rather than LOWTRAN 7. It is found that SST estimation error for MODTRAN 3.7 is 3 to 9 [%] better than that for LOWTRAN 7 because the atmospheric transparency of the atmospheric window bands are increased by around 2 [%] while the transparency of the water vapor absorption band is decreased by approximately 3 [%] due to the fact that the wavenumber step of MODTRAN 3.7 is better than that of LOWTRAN 7 (1 [cm-1] for MODTRAN 3.7, 5 [cm-1] for LOWTRAN 7) . Furthermore, it is found that 1.5 to 39.2 [%] of improvement on SST estimation can be achieved by adding band 10 to the rest of ASTER/TIR bands (11 to 14) . The band 10 is getting 59.3 [%] more effective on SST estimation by shifting to larger wave number by 25 [cm-1] from the current center wave number.
