CHLA-Z: Global Chlorophyll-a Vertical Distribution (0–200 m)
CHLA-Z is a global gridded dataset providing estimates of chlorophyll-a concentration as a function of depth (0–200 m) on a regular latitude/longitude grid, along with derived vertical-structure metrics. The product is generated using a boosted regression tree (BRT) model trained on PACE OCI Level-3 mapped remote-sensing reflectances (Rrs) and in-situ chlorophyll profile observations from Bio-Argo and OOI.
