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 No red-edge band, so no NDCI spectral
Landsat has no band near 705 nm. The green/blue ratio used instead is the open-ocean approach and is known to fail in turbid productive water - which is every water body in this study.
What to do: Treat the Landsat chlorophyll series as a RELATIVE index only, and never splice it to a Sentinel-2 NDCI series without the bias correction in 11_algae_daily_fill.py.
