熱赤外放射計による海面温度推定における最適波長選択

抄録

In order to get a best combination of the thermal infrared bands for Sea Surface Temperature (SST) Estimation, a simulation study is carried out by using LOWTRAN-7 of the atmospheric code with 1350 of parameters. As the results from the simulation study, it was found that longer wavelength region would be better compared to the NOAA/AVHRR Bands 4 and 5 when two bands are selected while 8.34 μm is the most adequate center wavelength when additional one band can be selected in addition to the originally selected two bands. Furthermore, a little bit shorter wavelength would be better compared to the NOAA/AVHRR band 3 when additional one band can be selected in addition to the selected three bands before that. Through the simulation study with LOWTRAN 7, 39.4% of improvement on SST estimation accuracy was achieved compar-ed to the accuracy with NOAA/AVHRR bands.
