SEAS5-Based SPI12 Data for Drought Assessment in the Lima River Basin

The Portuguese section of the Lima River Basin is the focus of this dataset containing monthly precipitation series, observed SPI12 values, and blended SPI12 forecasts. It includes hybrid blending configurations and forecast verification files used to evaluate ECMWF SEAS5 seasonal forecasts. Author Kenny Cevallos published the 314.4 KB dataset on figshare in April 2026.

Use Cases

• Evaluate the skill of SEAS5 seasonal forecasts for drought monitoring based on the described forecast verification outputs.
• Assess meteorological drought conditions based on the monthly precipitation and observed SPI12 series.
• Test hybrid blending methods for SPI12 forecasts based on the described 11+1, 10+2, 9+3, and 6+6 configurations.
• Develop drought early warning frameworks based on the 12-month SPI forecast data.

Strengths

• Dataset includes multiple forecast blending configurations (11+1, 10+2, 9+3, 6+6) for method comparison.
• Files are provided for forecast verification, allowing direct skill assessment of the SEAS5 model.
• Data is focused on a specific geographic region, the Portuguese section of the Lima River Basin.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is small at 314.4 KB, indicating a limited scope of records.
