Modelled urban climate island during the record-breaking 2022 heatwave in London

This record is created as a data supplement for the manuscript "Estimated mortality attributable to the urban heat island during the record-breaking 2022 heatwave in London". These data were produced using the Weather Research Forecasting model with BEP-BEM. The model setup is described in Brousse et al (2023) 10.1175/JAMC-D-22-0142.1. These data cover the period 2022-07-10 to 2022-07-25, during which temperatures exceding 40 °C were recorded in London for the first time. The data comprise two NetCDF files. One is labelled "Urb" one "Nourb". In the "Nourb" file, the urban tile is removed from the model and the land surface replaced by the nearest natural tile. This can be used to estimate the influence of the urban tile on the local climate. Variables included in the file are T2 (temperature at 2 m elevation in Kelvin), V10 and U10 (winds at 10 m elevation in metres per second), PSFC (surface level pressure in Pascal), RAINNC (rain in mm), TH2 (potential temperature at 2m elevation in Kelvin), and Q2 (specific humidity at 2 m elevation, which is dimensionless). All variables are provided at hourly timestep. Queries about this dataset can be directed to [e-mail]
