CHESS-met: 1km Gridded Daily Meteorology for Great Britain (1961-2015)

CHESS-met provides a 1-kilometer resolution gridded dataset of seven daily meteorological variables essential for running the JULES land surface model. Its 55-year time series from 1961 to 2015 is derived from high-quality sources like CEH-GEAR rainfall estimates and interpolated coarser data, corrected for errors in air pressure and daily temperature range. This dataset is specifically formatted for hydrological and ecological modeling applications over Great Britain.

Use Cases

• Running the JULES land surface model for energy and water flux simulations based on the required daily variable set.
• Historical climate trend analysis over Great Britain using the 55-year daily time series of temperature, humidity, and radiation.
• Hydrological modeling and water resource assessment leveraging the 1km gridded precipitation data scaled from CEH-GEAR.
• Spatial disaggregation studies or model validation using the high-resolution, topography-informed interpolated variables.

Strengths

• Offers a long, consistent 55-year daily time series from 1961 to 2015.
• Provides high spatial detail with 1-kilometer resolution gridded data over Great Britain.
• Corrects specific errors in air pressure and daily temperature range files for the period 2013-2015, superseding a previous version.
• Variables are specifically curated and scaled for compatibility with the widely-used JULES land surface model.

Limitations

• The dataset has been withdrawn on all listed platforms, indicating it may be deprecated or superseded.
• Key metadata such as row count, file size, license, and specific author are unavailable across sources.
• The spatial coverage is limited to Great Britain, excluding Northern Ireland and other regions.
