HeatLens is MEER's browser-based platform for physiologically informed heat-risk assessment. It converts local weather into thermal-comfort and heat-strain metrics using the HESTIA surface-energy engine, the PYROX exposure engine and the JOS-3 human thermoregulation model.

How does HeatLens compute heat risk?

HeatLens ingests atmospheric and surface data, computes WBGT, UTCI and mean radiant temperature (MRT) at your chosen location, then propagates those environmental fields through a validated physiological model to estimate core-temperature rise, sweat rate and heat-strain risk categories.

Which thermal indices does HeatLens use?

Wet Bulb Globe Temperature (WBGT), Universal Thermal Climate Index (UTCI) and Mean Radiant Temperature (MRT) — the three international standards for outdoor heat stress. Each links to its glossary definition.

Can HeatLens model passive cooling interventions?

Yes. HeatLens supports scenario runs for reflective canopies, cool roofs and reservoir covers so decision-makers can quantify the risk reduction from planned interventions before deployment.

City governments, humanitarian agencies, occupational-health teams, researchers and community organizations that need a defensible, physiology-based estimate of heat risk for a specific location and population.
