Lamto Rainy Season Onset and Cessation Data for West Africa, 1964-2023

Kouakou Kouadio's dataset provides daily rainfall data from 1964 to 2023 for Lamto, Côte d’Ivoire. It compares rainy-season onset, cessation, and duration using four diagnostic definitions (AGRHYMET, Stern, Sivakumar, Omotosho) for two annual seasons. The analysis includes time series, Mann–Kendall statistics, and Sen’s slope to assess interannual variability and long-term trends.

Use Cases

• Compare the sensitivity of rainy-season onset timing based on four different diagnostic definitions.
• Analyze long-term trends in rainy-season duration and cessation dates using Mann–Kendall statistics and Sen’s slope.
• Assess interannual variability and the likelihood of false starts in the first rainy season (March-July) versus the second (September-November).
• Support climate-informed agricultural planning by evaluating the reliability of onset signals across different methodological definitions.

Strengths

• Covers a long-term daily rainfall record from 1964 to 2023.
• Compares results from four established onset diagnostic methods (AGRHYMET, Stern, Sivakumar, Omotosho).
• Includes analysis of two distinct rainy seasons (March-July and September-November) with specific date ranges provided.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The 1.2 MB file size suggests the dataset is relatively small in scale.
