China County-Level Excess Heat Factor Metrics, 2011-2020

2011 to 2020 county-level annual Excess Heat Factor (EHF) metrics for China, created by Qianhui Shi. The dataset includes metrics such as the number of warm-season EHF days, average intensity, average temperature, and daily temperature variability, calculated against three temperature thresholds. It is accompanied by R code for the entire calculation process.

Use Cases

• Modeling heat-related health risks based on county-level EHF metrics.
• Analyzing temperature variability trends based on the `var` (daily temperature variability) metric.
• Assessing heatwave intensity and frequency based on `ehf_tday` (number of EHF days) and `ehf_avginten` (average intensity).
• Studying long-term temperature exposure based on `avg_temp` calculated over 2, 3, or 4-year periods.

Strengths

• Includes 10 years of data (2011-2020).
• Covers county-level spatial units across China.
• Provides accompanying R code for reproducibility of the EHF calculation.
• Calculates metrics against three specific temperature thresholds (p90, p92.5, p95).

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
