Carbon is one of the most important element on the earth, and it can become with key of the mechanism of earth fluctuation. Also, it is said that vegetation plays an important role of the carbon circulation of biosphere-lithosphere-atmosphere. Therefore, it is needed for environment monitoring to understand plant productivity globally. The Japan Aerospace Exploration Agency (JAXA; former NASDA) has successfully launched a new Advanced Earth Orbiting Satellite (ADEOS-II) aboard an H-2A booster on December 14, 2002. The ADEOS-II satellite is focused on monitoring of global climate change on the Earth. Four disiplinary components of the Earth system, namely atmosphere, ocean, cryosphere, and land, are monitored with five sensors onboard this satellite including the Global Imager (GLI). Unfortunately, the operation of ADEOS II satellite has stopped on October 24 of 2003, but very important VNIR/SWIR/MTIR data has been obtained in northern hemisphere for vegetation dynamics by GLI sensor. These data have enough capability to monitor the density and vigor of green vegetation. GLI data has high potential for vegetation monitoring, and it will contribute to the future satellite sensor. 23 channels are dedicated for land observations in the two spatial resolutions; channels 1, 5, 8, 13, 15, 17, 19, 24, 26, 27, 28(2km), 30, 31, 34, 35, and 36 are for 1 km resolution, and channels 20, 21, 22, 23, 28, and 29 are for 250 m resolution. This paper shows the preliminary evaluation of GLI land products for vegetation monitoring.
