Precipitation per MSOA in 2022
Dataset
Summary
Description:
This dataset provides comprehensive precipitation indicators aggregated to MSOA-equivalent geographies for the United Kingdom for 2022. The data is created from the HadUK-Grid dataset, a quality controlled gridded climate product produced by the Met Office at 1km spatial resolution (v1.3.1.ceda, 1836-2024). The dataset includes mean annual rainfall depth in mm, seasonal mean rainfall depth (winter, spring, summer, and autumn), annual precipitation anomalies, both absolute (mm difference from historical baseline) and standardised (divided by historical standard deviation), extreme rainfall indicators, including the number of days exceeding 4 standard deviations above the historical daily mean. Annual and seasonal values were aggregated from raster to MSOA using an area weighted mean. Extreme event indicators were first calculated at the pixel level using daily data and then aggregated to MSOA level.

The dataset contains the following variables: 'dt_zn_c' (MSOA zone code identifier); 'dt_zn_n' (MSOA zone name); 'rainfall_annual_mm' (mean annual rainfall depth in mm, area-weighted mean across pixels); 'winter_rainfall' (mean winter season rainfall depth in mm); 'spring_rainfall' (mean spring season rainfall depth in mm); 'summer_rainfall' (mean summer season rainfall depth in mm); 'autumn_rainfall' (mean autumn season rainfall depth in mm); 'annual_anomaly_abs' (absolute annual precipitation anomaly from historical baseline in mm); 'annual_anomaly_std' (standardised annual precipitation anomaly); 'extreme_days_4sd' (number of days where daily rainfall exceeded 4 standard deviations above historical mean); 'year' (reference year).

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 precipitation
variation. 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

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. Precipitation anomalies were calculated by comparing 2022 annual mean precipitation against the 1899-1900 baseline period mean and standard deviation for each pixel and then aggregate to the MSOA. The aggregation was performed using the MSOA-equivalent boundaries (2021) by calculating the weighted mean of all grid cells falling within each Middle Super Output Area (MSOA) geography.
