Heat Stress Monitoring for Outdoor Workers, Powered by EHI-N*
SHRAM provides real-time heat stress monitoring across India using EHI-N*, a physiologically-based model calibrated to MET levels developed by the IECC team. EHI-6* estimates heat stress experienced by workers doing heavy labor in direct sunlight.
View current conditions by district, 3-day forecasts, and sign up for personalized alerts when hazardous heat levels are detected.
CHAITRA – City Heat Action InTelligence and Risk Atlas Scaling evidence-based heat action planning in India
Heat Action Plans (HAPs) have evolved over the past decade into India’s principal framework for urban heat preparedness. Following national guidelines issued in 2016, many cities have established early warning systems, strengthened health system readiness, expanded public outreach, and, in some cases, developed vulnerability assessments and hotspot mapping.
EHI-N*: A Modified Extended Heat Index for Laboring Populations
Approximately 2.4 billion workers perform manual labor globally, yet current heat stress indices are calibrated to sedentary individuals, systematically underestimating risk for active workers.
Chaitra – Technical Specifications
CHAITRA is a ward-level decision support tool built on Google Earth Engine that can enable state and city officials to accelerate heat action planning, identify wards most at risk and estimate investment needed for different mitigation measures.
Scaling data-driven heat action planning using CHAITRA – City Heat Action Intelligence and Risk Atlas
Over 250 Indian cities have adopted Heat Action Plans (HAPs), but fewer than a handful include ward-level vulnerability assessments or translate risk data into quantified intervention needs.
Manual Work Under Extreme Heat: Using EHI-N* to protect laboring populations
India’s roughly 380 million outdoor and heat-exposed workers face escalating danger from extreme heat, yet the metrics used to declare heatwaves and trigger protective action systematically underestimate their risk.
The New York Times: How Many People Die in India From Hot Weather? Nobody Really Knows
Officials have yet to grasp the magnitude of heat-related deaths, let alone effectively deal with the problem, public health experts and scientists say.
National Advisory on the Extended HeatIndex-350 (EHI-350).
