Philippines Hydrology Projections from 1980-2089 with UKCP18 Scenarios

Philippines climate change scenarios from 1980 to 2089, using UKCP18 RCP 2.6 and RCP 8.5 pathways. The dataset contains 30 model runs from the Philippine National Hydrological model, simulating variables like evapotranspiration and runoff. It was provided by the British Geological Survey and last updated in April 2026.

Use Cases

• Projecting future water availability based on simulated runoff and river baseflow.
• Assessing climate change impacts on soil moisture and groundwater levels.
• Analyzing provincial-level hydrological changes using aggregated GADM subdivision data.
• Comparing outcomes between low (RCP 2.6) and high (RCP 8.5) emission scenarios.

Strengths

• Provides 30 model runs across two RCP scenarios, each with 15 ensemble members.
• Covers a long-term projection period from 1980 to 2089.
• Includes multiple hydrological variables like evapotranspiration, runoff, and soil moisture.
• Offers data aggregated to provincial level for easier regional analysis.

Limitations

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