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.

Why not — catalogue limitation. Too short for a 2000-2026 time series. Use as a high-quality validation snapshot for the recent period, or for a methods paper.

Typed limitations (1)
MEDIUM PACE launched 2024 - a very short record temporal
Best pigment discrimination available anywhere, and only about two years of data inside the study window.
What to do: Not usable for the time-series analysis. Worth one figure as a demonstration of what hyperspectral adds.
