Algae Dataset
Every data hub, dataset, sensor, variable, paper and limitation in one tree — and for each: where it comes from, how far back it goes, how often it captures, why it belongs in a cholera study, and why it does not work everywhere.

HIGH IRI is a strong climate archive but a thin ocean-colour one coverage
The Ingrid engine is excellent for SST, rainfall and climate indices, with some records reaching the 1850s. Its NASA/PO-DAAC/oceancolor branch is sparse and inconsistently maintained.
What to do: Use IRI for ERSST v5, CHIRPS daily rainfall and CAMS-OPI. Get chlorophyll from ERDDAP, CMEMS or GEE. Note also that Ingrid time bounds are month-granular even for daily data.
