Abstract

Japan Aerospace Exploration Agency (former NASDA) has successfully launched a new Advanced Earth Orbiting Satellite (ADEOS-II) aboard an H-2A booster on December 14, 2002. ADEOS-II is designed to monitor global climactic change through researches of the Earth's environment. GLI, which is one of five sensors, has high potential for vegetation monitoring, and it will contribute to the future satellite sensor. GLI has 23 channels in VNIR which include 380nm channel, 6 channels in SWIR, and 7 channels in MTIR. And this sensor has two kinds of spatial resolution, which are 1km and 250m. GLI 380nm channel is very unique channel, which can be sensitive for aerosol over land. GLI land higher level processing includes precise geometric correction, 16-day composite, atmospheric correction, and vegetation index (NDVI and EVI). However, GLI atmospheric correction for land is conducted for only Rayleigh scattering and Ozone absorption. Therefore, this atmospherically corrected NDVI is affected by aerosol over land. On the other hand, 380nm data has the capability of removal of aerosol over the land. The difference between TOA NDVI and the new NDVI subtracted 380nm can be a function of optical thickness of aerosol. This paper shows that the evaluation of aerosol correction over the land by using GLI 380nm reflectance.
