Ocean Temperature Analysis: sea-surface temperature and subsurface heat

Ocean Temperature Analysis

Daily SST, anomalies, and record composites across 17 regions from NOAA OISST v2.1 and Coral Reef Watch, plus TCHP and 26 °C isotherm depth (D26) subsurface fuel from NOAA AOML and CMEMS ARMOR3D.

What is this?

Triple-A-Tropics is a real-time dashboard for tracking tropical cyclone activity. It ingests official best-track data from NOAA's IBTrACS archive and JTWC's live b-decks, computes statistics like Accumulated Cyclone Energy (ACE), and publishes the result as interactive visualizations. Subsurface heat products are rebuilt daily from NOAA AOML, with weekly cross-sections and TCHP anomalies layered in from CMEMS ARMOR3D reanalysis.
