CHLA-Z v0.1.0 — Draft global chlorophyll-a vertical distribution dataset

This is the initial public draft release of CHLA-Z, a global gridded dataset describing chlorophyll-a vertical structure (0–200 m) derived from PACE OCI remote-sensing reflectances and in-situ Bio-Argo observations using a boosted regression tree (BRT) model.

This release is intended to establish provenance, citation, and a stable access point for the dataset and associated documentation. The large CHLA-Z data files are hosted separately in public Google Cloud Storage and are not archived directly in this release.

Included in this release:

• Dataset landing page and documentation (in docs folder)
• Notebooks with the exact pipelines used to create the dataset
• Example analysis notebooks (Python / Colab / R)
• Metadata describing variables, grid, and access patterns
• Model configuration and supporting utilities
• Training data subsets, model configuration, and supporting utilities

Data access:

• Zarr v3 (cloud-optimized): gs://nmfs_odp_nwfsc/CB/fish-pace-datasets/chla-z/zarr
• Daily NetCDF files: gs://nmfs_odp_nwfsc/CB/fish-pace-datasets/chla-z/netcdf

Status:
This is a research/draft product. Validation, uncertainty characterization, and finalized methods documentation are in progress. In particular the training data are currently limited to Bio-Argo and OOI and we are activitely working to increase the training data (in-situ CHLA at depth) from other platforms.

Variable names, grid definition, and access paths are expected to remain stable; algorithm details and derived metrics may evolve in subsequent versions. This release is intended for exploratory analysis, method evaluation, and early scientific use.

Please cite this specific release DOI for reproducibility. A concept DOI representing the CHLA-Z dataset as a whole will always resolve to the latest version.
