Gridded datasets of daily rainfall amount (millimetres) and daily maximum, minimum and mean air temperature (degree Celsius), covering the UK at 5 km x 5 km resolution, for the period 1960 to 2011.
The Met Office archive of daily observations has been used as the main input to the analysis. Geographical effects such as latitude and longitude, altitude, coastal influence, and the effect of urban land use were incorporated through normalisation with respect to monthly 1961-1990 climate normals and, in the case of temperature, a regression model. Station values were then interpolated onto the regular grid using inverse distance weighted interpolation.
Both the input station data, and the gridded output have been quality checked. Checking of the output focussed on an analysis of regression residuals for temperature, and on visual inspection of the grids for rainfall. The methods used to generate the daily grids are described I more detail in ,  and .
