ADEOS-I OCTS Level-3 Global Binned Chlorophyll (CHL) Data, version 2022.0

The Chlorophyll-a data suite provides global, gridded composites of surface chlorophyll-a concentration (a proxy for phytoplankton biomass). CHL supports time-series and climatologies, anomaly detection, ecosystem and fisheries applications, and teaching/training, and pairs well with AVW, PAR, Kd(490), SST, and winds for environmental context. Note: retrievals in optically complex coastal/inland waters may carry higher uncertainty—refer to the mission/algorithm documentation (e.g., OCx/OCI) for details.

Geophysical variables in this suite include: - chlor_a — Chlorophyll-a concentration (mg m⁻³)
