El Nino Watch

NASA Earth Observatory stories

NASA's daily satellite image story, kept only when it is about El Nino impacts.

Data and trust

NASA Earth Observatory publishes one explained satellite image per working day. The app keeps the ones about El Nino, drought, heat, fire and haze, floods, storms, coral bleaching, the oceans or Southeast Asia.

Limits. Only the last ~10 stories are in the feed; many days have no matching story, which is normal.

How to read it

Each item links to the article; titles stay as published.

Why it matters for Koh Samui

Good plain-language explanations with pictures of what El Nino does around the world.
