Summary
Description:
This dataset provides comprehensive temperature indicators aggregated to small-area geographies equivalent to Middle Super Output Area (MSOA) level for the United Kingdom. The dataset includes annual temperature measures for 2023, seasonal indicators (summer 2023 and winter 2023/24), extreme weather event indicators (hot and cold spells), temporal variability measures, and temperature anomalies relative to a 1884-1900 baseline. The underlying source data is the HadUK-Grid Gridded Climate Observations at 1km spatial resolution (v1.3.1.ceda, 1836-2024), published by the Met Office Hadley Centre for Climate Science and Services. The aggregation was performed using the MSOA-equivalent boundaries (2021) by calculating the weighted mean of all grid cells falling within each MSOA-equivalent geography.
**IMPORTANT** - This is a beta version of the data product. We have released it as a preview to allow users exploration and experimentation while we perform final quality assurance and additional checks. If you encounter any issue or have questions, please get in touch with us at [imago@liverpool.ac.uk](mailto:imago@liverpool.ac.uk) We will shortly be releasing a more stable version. Please check [https://imago.ac.uk](https://imago.ac.uk) for news and updates.

Documentation
Documentation:
The dataset contains 13 temperature-related variables for each Middle Super Output Area (MSOA): (1) Annual measures: mean, maximum, and minimum temperatures; (2) Seasonal measures: summer mean and maximum temperatures (June-September 2023), winter minimum temperature (November 2023-March 2024); (3) Temporal variability: standard deviation across monthly temperatures; (4) Extreme event indicators: number of extreme hot days (≥30°C), number of 3-day hot spells (≥25°C), number of extreme cold days (≤0°C), and number of 3-day cold spells (≤2°C), reported as both mean values within each MSOA; (5) Climate anomaly measures: temperature anomalies relative to 1884-1900 baseline: absolute anomaly in degrees Celsius and standardized anomaly in standard deviations. Geographic identifiers include MSOA-equivalent regional codes and names. This data is provided in two distinct formats: a CSV file, which contains the tabular data; and a GPKG file, a geospatial format that combines the tabular data with the MSOA-equivalent boundary geometries.

Purpose:
HadUK-Grid data are quality-controlled observational data interpolated to a 1km
grid. Coverage might differ across England, Wales, and Scotland depending on
ground-station coverage, with slightly lower station density in Northern Ireland
and remote areas. Temporal standard deviations capture seasonal temperature
variation. Hot and cold spell indicators are based on established threshold
definitions aligned with UK Met Office and UK Health Security Agency criteria.
It is important to note that the underlying input data has a spatial resolution
of 1km x 1km, which should be considered when interpreting results for
administrative areas finer than this scale. Further technical details are
available in the HadUK-Grid documentation at:

- This version is released as beta. This means that, although we have applied
our quality standard in its production, we are still assessing its overall
quality and identifying minor issues that need resolution before a more stable
version can be released. As soon as we are ready, we will issue a new release.

Source:
The underlying data source is the HadUK-Grid dataset, a comprehensive collection of gridded climate observations produced by the Met Office Hadley Centre for Climate Science and Services. HadUK-Grid combines quality-controlled observations from the UK Met Office's weather station observations and uses natural neighbour interpolation to generate a regular 1km grid. The dataset is described in: Hollis, D., McCarthy, M., Kendon, M., Legg, T., Simpson, I. (2019): HadUK-Grid—A new UK dataset of gridded climate observations. Geoscience data journal, 6(2), 151-159. DOI: https://doi.org/10.1002/gdj3.78. Daily maximum temperatures were used to identify hot spells (3+ consecutive days ≥25°C or single days ≥30°C during June-September 2023). Daily minimum temperatures were used to identify cold spells (3+ consecutive days ≤2°C or single days ≤0°C during November 2023-March 2024). Temperature anomalies were calculated by comparing 2023 annual mean temperatures against the 1884-1900 baseline period mean and standard deviation for each pixel and then aggregate to the MSOA. The MSOA aggregation was performed by the Imago Team using exact extraction methods with area-weighted statistics.
