1 km gridded estimates of daily and monthly rainfall for Great-Britain and Northern Ireland (together with approximately 3000 km2 of catchment in the Republic of Ireland) from 1890 to 2019. The rainfall estimates are derived from the Met Office national database of observed precipitation. To derive the estimates, monthly and daily (when complete month available) precipitation totals from the UK rain gauge network are used. The natural neighbour interpolation methodology, including a normalisation step based on average annual rainfall, was used to generate the daily and monthly estimates. The estimated rainfall on a given day refers to the rainfall amount precipitated in 24 hours between 9am on that day until 9am on the following day. The CEH-GEAR dataset has been developed according to the guidance provided in BS 7843-4:2012.

This dataset contains a timelapse video of a tracer percolation experiment in the seasonal snowpack near Ny-Alesund, Svalbard, on 31st March 2023. The tracer percolation experiment was carried out by applying a coloured water tracer over a defined area and filmed using a camera and tripod. The video was recorded as part of an experimental field study ("Wet Finderprints") by Dorothea Moser to visualise the progression and retardation of meltwater liquid in near-surface snow. The project was supported by an Arctic Field Grant through the Norwegian Research Council - Project No. 342165, RiS ID 12132. Dorothea Elisabeth Moser was supported by BAS Cambridge and the NERC C-CLEAR Doctoral Training Programme (grant no. NE/S007164/1).
