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.

VALIDATION limitations
CRITICAL No in-situ chlorophyll anywhere in the project validation
Without paired field measurements, NDCI, FAI and the phycocyanin proxy are ordinal indices, not concentrations. Reviewers will treat every inland number as uncalibrated. This is the single largest weakness in the study and it is fixable comparatively cheaply.
What to do: Three asks, cheapest first: BORI Cox's Bazar coastal monitoring, Department of Fisheries shrimp-pond water-quality logs, and the open GLORIA hyperspectral archive. Even 30-50 paired observations move three products from tier C to tier A.
HIGH Landsat green/blue chlorophyll proxy is uncalibrated validation
The ratio responds to chlorophyll but the relationship is scene-specific and unvalidated for Bangladeshi water. Absolute values carry no physical meaning.
What to do: Use it for RELATIVE change and phenology only. Always state it as an index and never report it in mg/m3.
