This dataset contains over 72,000 event hyetographs associated with rainstorms that contain Annual Maximum rainfall (AMAX) values for durations between 5-min and 24-hr for a set of ~1,300 rain gauges in Great Britain. The record length and completeness varies on a gauge-by-gauge basis, the median record length is 19 years and the processed record ends in 06/2018. Note that a rainstorm may have a different duration to the associated AMAX value, e.g., a 24-hr AMAX total may be caused by an 18.25-hr event. Further note that multiple AMAX totals may be embedded within a single rainstorm, e.g., Storm Desmond can be associated with the 2-, 3-, 6-, 12- and 24-hr AMAX totals for 2009 recorded at Honister Pass. Each hyetograph is accompanied by summary statistics corresponding to the underlying rainstorm and associated AMAX totals. This dataset enables the study of the temporal characteristics of rainfall as well as more general studies regarding the climatology of AMAX-causing events in GB.

Prediction of Caesium-137 (Cs-137) deposition from atmospheric nuclear weapons tests. The methodology uses a ratio of Cs-137 deposition and precipitation measured at Milford Haven by the Atomic Energy Authority extrapolated across Great Britain using a 5 by 5 km resolution UKCIP precipitation dataset. The prediction is for 31 December 1985. Full details about this dataset can be found at https://doi.org/10.5285/c3e530bf-af20-43fc-8b4b-92682233ff08

1km and 5km gridded Standardised Precipitation-Evapotranspiration Index (SPEI) data for Great Britain, which is a drought index based on the probability of Climatic Water Balance (CWB) - which is equivalent to the amount of precipitation minus the amount of evapotranspiration - for a given accumulation period as defined by Vicente Serrano et al. (2010). SPEI is calculated for different accumulation periods: 1, 3, 6, 12, 18, 24 months. Each of these is in turn calculated for each of the twelve calendar months. Note that values in monthly (and for longer accumulation periods also annual) time series of the data therefore are likely to be autocorrelated. The standard period which was used to fit the generalised logistic distribution is 1961-2010. The dataset covers the period from 1961 to 2012.

This dataset provides weekly pollutant concentration and deposition data in cloud and rain samples from the, now retired, Bowbeat field site near Edinburgh, UK. The data were captured approximately weekly between 03/09/2003 and 28/06/2006 using a cloud droplet collector and rainwater collector. They were collected to monitor and model cloud/rain water composition and deposition at high elevation as part of ongoing routine measurements.

[THIS DATASET HAS BEEN WITHDRAWN]. 1km resolution gridded meteorological variables over Great Britain for the years 1961-2015. This dataset contains time series of daily mean values of air temperature (K), specific humidity (kg kg-1), wind speed (m s-1), downward longwave radiation (W m-2), downward shortwave radiation (W m-2), precipitation (kg m-2 s-2) and air pressure (Pa), plus daily temperature range (K). These are the variables required to run the JULES land surface model [1] with daily disaggregation. The precipitation data were obtained by scaling the Gridded estimates of daily and monthly areal rainfall (CEH-GEAR) daily rainfall estimates [2,3] to the units required for JULES input. Other variables were interpolated from coarser resolution datasets, taking into account topographic information. This release supersedes the previous version [4], doi:10.5285/10874370-bc58-4d23-a118-ea07df8a07f2, as it corrects errors in the air pressure and daily temperature range files for 2013-2015.
