ADEOS-II/GLI L2 Cloud flag
Listed in NASA Earthdata CMR
ADEOS-II/GLI L2 Cloud flag 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 is cloud mask data which indicate whether a given view of the earth surface is unobstructed by clouds or optically thick aerosol, and whether that clear scene is contaminated by a shadow, and L1B data is used as input data. The provided format is HDF.
The physical quantity unit is None. The generation unit is global. Map projection is not done.
The spatial resolution is 0.25 degree and the statistical period is 4 days. This product also includes Day/Night Flag, Sunlit Flag, Snow / Ice background Flag and Land/Water Flag. Note that this product has an error for "L1B_bound" data.
L1B_bound is a parameter that decides whether or not the granule scene of L1B data crosses the boundary of latitude and/or longitude. As an alternative, CLFLG_P has attribute information that includes the latitude and longitude of four corners of the granule scene that can be used for the same decision. Hence, we do not plan to reprocess CLFLG_P to correct this error.
Please use CLFLG_P to resolve this issue. The current version of the product is "Version 2".
