Hydro-PE HadUK-Grid: UK Potential Evapotranspiration at 1km Resolution

United Kingdom gridded potential evapotranspiration data at 1 km spatial resolution from 1969 to 2024. It contains two daily variables: total potential evapotranspiration (PET) and a version with interception correction (PETI), provided in netCDF format with monthly files. The data were generated from HadUK-Grid meteorological observations as part of the Hydro-JULES research project.

Use Cases

• Modeling hydrological water balance based on daily potential evapotranspiration estimates.
• Assessing agricultural drought risk using gridded PET data at 1 km resolution.
• Calibrating land surface models with interception-corrected evapotranspiration (PETI) data.
• Analyzing long-term climate trends in evaporative demand across the United Kingdom from 1969 onward.

Strengths

• High spatial resolution of 1 km for detailed regional analysis across the UK.
• Long temporal coverage spanning over 50 years, from 1969 to 2024.
• Provides two related variables (PET and PETI) for comparative analysis.
• Data generated under a specific NERC research grant (NE/S017380/1), indicating a research-grade origin.

Limitations

• Metadata conflict: some platform entries indicate the dataset is withdrawn for the period 1969-2020, while another lists an active version extending to 2024.
• Sparse metadata: specific column names, row counts, file sizes, and license information are not provided in the input.
• Data format (netCDF) may require specialized software or knowledge for access and analysis.
