ADEOS-II/GLI L3 STA Map Vegetation Index product
Listed in NASA Earthdata CMR
ADEOS-II/GLI L3 STA Map Vegetation Index (16days,1/12deg)is obtained from the GLI (Global-Imager) sensor onboard ADEOS-II and produced by the Japan Aerospace Exploration Agency (JAXA).
Description
Global environment change has become a worldwide concern in recent years. In order to clarify these environmental changes, the Advanced Earth Observing Satellite (ADEOS-II, renamed "Midori II" after launch) has been developed for the purpose of monitoring the Earth environment using remote sensing technology from space.
Midori II carries mission instruments that are particularly dedicated to clarify the water energy cycle and the carbon cycle, and is expected to be utilized for international climate change research programs. GLI an optical sensor that observes the reflected solar radiation from the Earth's surface, including land, oceans and clouds and/or infrared radiation with a multi-channel system for measuring the biological content.

The SGLI has a swath of 1600 km. This product includes the normalized difference vegetation index (NDVI) which is the ratio between the difference in the red and near- infrared and their sum the most widely used index in global vegetation studies and the enhanced vegetation index (EVI) for increased sensitivity over a wider range of vegetation conditions, removal of soil background influences, and removal of residual atmospheric contamination effects present in the NDVI.
This product is generated from Level-2 product. All zone of Level-2 product is connected and northern and southern polar stereographic region is projected to equi-rectangular. Level 3 STA Map product of land is the representative values, which are estimated from level 2 binned product and projected onto map.
As for the estimation arithmetic mean method is applied.The provided format is HDF. The spatial resolution is 1/12 degree and the statistical period is 16 days. Map projection is EQR.
The generation unit is global. The current version of the product is "Version 2".
