HeatLens
HeatLens turns raw weather data into a clear picture of what heat actually does to people. It combines local climate inputs with human physiology models to show where and when heat becomes dangerous — and how much passive cooling can reduce that risk.
Scientific detail
HeatLens is a heat-risk assessment platform built on MEER's HESTIA (surface energy and thermal comfort) and PYROX (population heat-exposure) engines. It ingests reanalysis and station observations, computes WBGT, UTCI and MRT, propagates them through JOS-3 physiological modeling, and outputs zone-level exposure and strain metrics. HeatLens supports scenario testing for reflective interventions, giving policymakers and NGOs a quantitative basis for prioritizing deployments.
