Description
Satellite-derived ocean color data from the GLI sensor onboard the ADEOS-II satellite, produced by the Japan Aerospace Exploration Agency (JAXA). It includes measurements of Chlorophyll-a concentration, attenuation at 490 nm, suspended solid concentration, and CDOM absorption at 440 nm. The data was last updated in October 2003 and has a spatial resolution of approximately 4 km.
Use Cases
Estimating phytoplankton biomass by analyzing Chlorophyll_a concentration values.
Assessing water clarity and light penetration in the ocean using the Attenuation at 490 nm feature.
Monitoring sediment transport and coastal turbidity via the Suspended solid concentration data.
Studying dissolved organic matter dynamics in seawater using CDOM absorption at 440nm measurements.
Strengths
Data has a spatial resolution of approximately 4 kilometers.
Sensor has a wide observation swath of 1600 km.
Product is a processed Level 2 dataset derived from raw sensor data.
Limitations
Data is temporally stale, with the last update in 2003.
Map projection is not applied to the data, requiring additional processing for geospatial analysis.
Specific row count, geographic coverage, and temporal range are not provided.
