ETCCDI Temperature-Extreme Indices for the Middle East, 1985-2100

ETCCDI temperature-extreme indices were generated by Younes Khosravi for a manuscript on projected climate extremes. The dataset contains four derived indices—TN90p, TX90p, TNx, and TXx—calculated from refined CMIP6 daily temperature fields for a historical baseline (1985–2014) and three future periods (2015–2100) under SSP scenarios. It was last updated on June 4, 2026.

Use Cases

• Assess future changes in warm nights and days based on the TN90p and TX90p percentage indices.
• Analyze spatial patterns of hot-day and warm-night intensity using the TNx and TXx seasonal maximum indices.
• Perform spatial autocorrelation and hotspot detection for temperature extremes across the Middle East.
• Investigate day-night asymmetry in temperature extremes by comparing derived index products.
• Validate or compare climate model projections using the processed ETCCDI index outputs.

Strengths

• Includes four specific, well-defined ETCCDI indices (TN90p, TX90p, TNx, TXx) for analysis.
• Covers a long temporal range from a historical baseline (1985–2014) to future projections up to 2100.
• Provides data under three standard Shared Socioeconomic Pathway scenarios (SSP1-2.6, SSP2-4.5, SSP5-8.5).
• Dataset size is 62.6 MB, suggesting a manageable download for the derived products.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
