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 Copernicus LWQ300 lake mask may exclude all three sites coverage
The Lake Water Quality product only reports for water bodies in its predefined mask at 300 m. Coastal lagoons are often excluded by design.
What to do: Verify coverage for your specific polygons first. If absent, this product contributes nothing and should be dropped from the plan.
