Data & Tools

Operational platforms and research products we develop and maintain for Southern African climate science.

Featured Tool

Live

ENSO Explorer

Interactive tool for exploring how rainfall, temperature, evaporative demand, drought and rainy-season timing across Southern Africa have historically responded to El Niño, La Niña and Neutral conditions. Auto-loads the latest NOAA forecast and maps the historical signal by phase, strength and season across the SADC region.

✓El Niño / La Niña / Neutral analysis by event strength
✓Rainfall, temperature, reference ET, SPEI, WRSI, dry spells and season timing
✓Composite, percent-of-average and frequency map views
✓Auto-loads the latest NOAA CPC forecast
✓National and provincial coverage across the SADC region
✓Experimental decision-support brief with downloadable PDF

Botswana Seasonal Rainfall Monitoring Portal

Operational seasonal rainfall monitoring platform for Botswana. Automatically updated rainfall maps and time-series derived from blended CHIRPS satellite data and surface station observations. Methodology aligned with the UCSB Climate Hazards Center's Early Estimates approach, adapted for Botswana with BDMS station data.

Subtropical Indian Ocean Dipole

A dedicated tracker for the Subtropical IOD, a climate mode uniquely consequential for Southern African summer rainfall and currently under-represented in global climate-mode monitoring. Extends and complements existing ENSO and tropical IOD products with a Southern Africa-specific lens.

Coming soon

Combined Drought Index

A multi-indicator drought monitoring tool combining CHIRPS-based rainfall deficits, vegetation stress, and soil moisture anomalies into a single composite index for Southern Africa, designed to support convergence-of-evidence drought assessments at national and sub-national scales.

Coming soon

AtmosViz

Visualization tools for the large-scale atmospheric circulation features that shape Southern African seasonal rainfall, including tropical-temperate troughs, the Botswana High, the Angola Low, and low-level moisture transport. Designed to support training and operational interpretation of forecast products.
