Weather Data for Insurance Risk Assessment
Insurance companies are increasingly relying on granular weather and climate data to price risk accurately. Traditional methods that use broad geographic zones and historical claims data are being replaced by location-specific climate risk models that consider flood exposure, wind patterns, precipitation extremes, and terrain characteristics. PixelGust provides the data foundation for this type of analysis.
For insurers: Use the PixelGust API to bulk-assess climate risk across property portfolios. Combine weather history, terrain, hazards, and proximity data for comprehensive risk scoring.
Climate Risk Factors for Insurance
Flood Risk
Flood is the most common and costly natural hazard for property insurance. PixelGust assesses flood susceptibility using the Topographic Wetness Index (TWI), which combines terrain slope and upstream catchment area to identify locations where water naturally accumulates. Combined with historical precipitation data, this provides a robust flood exposure estimate.
Key data points: TWI, elevation, slope, historical precipitation (monthly totals and extremes).
Wind Damage Risk
High wind speeds cause roof damage, fallen trees, and structural failures. PixelGust provides 10 years of historical wind speed data, showing both average conditions and peak events. Properties in areas with consistently high wind speeds or frequent storms carry higher risk.
Key data points: historical wind speed (monthly mean and maximum), wind direction patterns.
Extreme Heat
Extended heat waves stress building materials, increase fire risk, and cause cooling system failures. The 10-year historical temperature record reveals locations prone to extreme heat events, with monthly maximum temperatures highlighting the worst-case exposure.
Key data points: historical temperature (monthly mean and maximum), solar radiation.
Soil Erosion
Erosion undermines foundations, damages roads, and destabilizes slopes. PixelGust's RUSLE-based erosion risk assessment combines rainfall intensity, slope, soil type, and vegetation cover to estimate annual soil loss potential.
Key data points: RUSLE erosion risk rating, slope, land cover, precipitation.
Building a Risk Score
Using PixelGust data, you can construct a composite risk score for any property:
- Flood score: Based on TWI (high TWI = high risk) and historical precipitation intensity.
- Wind score: Based on historical maximum wind speeds and frequency of high-wind events.
- Heat score: Based on historical maximum temperatures and heat wave frequency.
- Erosion score: Based on RUSLE soil loss estimate.
- Access score: Based on proximity to emergency services (hospitals, fire stations).
Weight each factor according to your underwriting criteria and combine them into a single risk rating. The PixelGust API enables this at scale, processing thousands of property coordinates per day.
Portfolio-Level Assessment
For insurance companies managing large property portfolios, PixelGust offers two approaches:
- API integration: Send property coordinates programmatically and receive risk data in JSON format. Process your entire portfolio overnight.
- Portfolio reports: Use the dashboard's multi-location feature to generate comparative reports across multiple properties. Export to Excel for further analysis.
Regulatory Compliance
Insurance regulators increasingly require climate risk disclosure. The EU's Solvency II framework and EIOPA guidelines ask insurers to demonstrate they understand climate-related risks to their portfolios. PixelGust data provides the quantitative evidence needed for these disclosures, backed by established scientific datasets (ERA5, Copernicus DEM, MODIS).
