Modelled daily soil moisture and soil temperature at 1km resolution across the UK mainland, 1965-2018
This dataset contains model outputs of daily mean volumetric water content and topsoil temperature at 1 km resolution across the UK mainland for the years 1965-2018. The outputs are generated using neural network models trained on COSMOS-UK (cosmic-ray soil moisture) observational data. The data are presented in monthly NetCDF files on the British National Grid.

Provenance & quality
The driving meteorology used to produce the outputs were from the CHESS-met dataset. Specifically, the inputs required to generate topsoil temperature outputs are: current day and previous day driving meteorology (temperature, total precipitation, longwave radiation, shortwave radiation, and the sunlight-hours average shortwave radiation); soil type vector (normalized ratios of five classes: sand, silt, clay, chalk, peat); soil organic carbon; bulk density of soil; land cover vector; elevation. There is an optional input of the MODIS 1 km Land Surface Temperature satellite product Day and/or Night values. The output of the topsoil temperature model is used as input to the soil moisture model.
The inputs required for the soil moisture model are: daily driving meteorology (temperature, pressure, total precipitation, relative humidity, longwave radiation, shortwave radiation, wind speed, and the sunlight-hours average shortwave radiation); soil type vector (normalized ratios of five classes: sand, silt, clay, chalk, peat); soil organic carbon; bulk density of soil; base flow index from the hydrology of soil types (BFIHOST); land cover vector; soil temperature; elevation. There is an optional input of the daily 1 km Soil Water Index satellite product from Copernicus.
Volumetric water content values in the COSMOS-UK data (TDT point probes and neutron sensor) that were higher than 90% were removed from the training set. The COSMOS-UK site Tadham Moor was removed from the training set after visual inspection of the TDT and neutron sensor data.
