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.

Strength. The Landsat archive back to 1984 - the only way to reach 2000-2015 at 30 m.

Weakness. 16-day revisit per satellite, and Landsat 7 has the SLC-off gap after 2003.

Use it for. GEE mirrors the same Collection 2 Level-2 data, so use GEE unless you need scenes locally.
