Product Summary

ADEOS-II/GLI L2A Ocean and Atmosphere is obtained from the GLI (Global-Imager) sensor onboard ADEOS-II and produced by the Japan Aerospace Exploration Agency (JAXA). 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 is a basic product for atmosphere and ocean level 2 products. Level 2A_OA consists of 4 pixel/4 line sampled all 1km GLI ch. Data, auxiliary data for atmosphere and ocean, cloud flag data and deviation table for removed data. The scene separated level 1B images are connected to tilt segment and eliminated overlapped scan lines.
Map projection is not performed. MTIR ch. data are filled in path, but VNIR and SWIR data are filled in only half path because they are worked only in daytime. All GLI channels except 250m resolution ch. are included. (ch.1-19, 24-36: although ch.28, 29 are 250m resolution, 2km sampled data are also acquired) The provided format is HDF. The current version of the product is "Version 2".
