Triple Jeopardy mapping estimates heat-related mortality in London by combining urban heat island effects, indoor temperature anomalies, and population age vulnerability. The dataset includes four layers of mortality estimates per million population over a 55-day period in 2006, including a four-day heatwave. It was produced by the Greater London Authority and last updated on March 25, 2026.
Use Cases
- Modeling localized heat mortality risk based on combined indoor and outdoor temperature exposure.
- Identifying wards with higher vulnerability based on the indoor temperature anomaly layer.
- Assessing the separate contributions of the urban heat island effect and building overheating to mortality.
- Prioritizing public health interventions using ward-level mortality estimates per million population.
Strengths
- Integrates three distinct risk factors: urban heat island, indoor temperature anomalies, and population age.
- Provides four specific mortality estimate layers, including HeatMortpM, HeatMorUHI, and HeatMorInd.
- Based on a defined 55-day period from May 26 to July 19, 2006, which included a heatwave.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Data is from a specific 2006 period; applicability to current or future climate conditions may be limited.
- Row count and file formats are unknown, which may limit suitability assessment.
