Overview

This platform provides interactive visualization of global sea surface temperature (SST) data. It currently supports monthly SST analysis, while the daily and yearly modules are under development.

Data Sources

ERSSTv6 — Monthly observed SST used for historical comparison and climatological reference.
NMME Ensemble Forecast — Multi-model seasonal forecast guidance used for monthly SST outlooks.
Temporal coverage combines historical observations with the latest available forecast initialization.

Methodology

Area-weighted means are calculated for each ocean domain, accounting for the convergence of meridians at the poles.
Climatological reference period: 1991–2020 (current 30-year climate normal recognized by WMO).
Monthly climatologies are derived from observed SST datasets and ensemble forecast products.

Visualization Features

Multi-year comparison with historical data overlay
Interactive chart with zoom, pan, and data export
Responsive design for desktop, tablet, and mobile devices
Forecast spread bands highlighting ensemble uncertainty

About the Project

This is a research project for ocean climate data visualization and analysis. The platform is developed for research and educational purposes at Southern University of Science and Technology (SUSTech).
