  • The 50km gridded resolution data for four climate projection scenarios produced in support of the UK Climate Impacts Programme 2002 (UKCIP02). There are data for monthly and seasonal average anomalies with respect to simulated 1961~90 average for four alternative future climates for the UK. The four emissions scenarios are Low (LO), Medium-Low (ML), Medium-High (MH) and High (HI). The monthly time-slice data are available for the following variables: Maximum temperature (TMAX), Minimum temperature (TMIN), Daily mean temperature (TEMP), Total precipitation rate (PREC), Snowfall rate (SNOW), Wind speed (WIND), Relative humidity (RHUM), Total cloud in longwave radiation (TCLW), Net surface longwave flux (NSLW), Net surface shortwave flux (NSSW), Total downward surface shortwave flux (DSWF), Soil moisture content (SMOI), Mean sea level pressure (MSLP), Surface latent heat flux (SLHF), Specific humidity (SPHU), Inter-annual variability: temperature (IAVT) and Inter-annual variability: precipitation (IAVP). The data are available over the following time periods using the following convention in the filename: 6190 = 1961 to 1990, i.e. observed climate, 2020s = predictions for 2011 to 2040, 2050s = predictions for 2041 to 2070, 2080s = predictions for 2071 to 2100.

  • 5km gridded resolution data for four climate projection scenarios, produced in support of the UK Climate Impacts Programme 2002 (UKCIP02) by the Met Office Hadley Centre. There are data for monthly and seasonal average anomalies with respect to simulated 1961~90 average for four alternative future climates for the UK. The four emissions scenarios are Low (LO), Medium-Low (ML), Medium-High (MH) and High (HI). Monthly data for cloud, precipitation (prec), temperature (temp), maximum temperature (tmax), minimum temperature (tmin) and wind are available using the following convention in the filename: 2020s = predictions for 2011 to 2040, 2050s = predictions for 2041 to 2070, 2080s = predictions for 2071 to 2100.

  • These data have been created by the Department for Environment, Food and Rural Affairs (Defra) and Joint Nature Conservation Committee (JNCC) in order to cost effectively provide high quality, Analysis Ready Data (ARD) for a wide range of applications. The dataset contains modified Copernicus Sentinel-1 data processed into a normalised radar backscatter product on a linear scale in dB. Products acquired from ESA are Ground-Range Detected (GRD) Interferometric Wide-swath (IW) in the dual VV+VH polarisation (DV) mode, where both VV and VH polarisations are collected. Defra and JNCC data were processed on separate platforms using a common specification to produce complementary outputs.

  • These data have been created by the Department for Environment, Food and Rural Affairs (Defra) and Joint Nature Conservation Committee (JNCC) in order to cost-effectively provide high quality, Analysis Ready Data (ARD) for a wide range of applications. The dataset contains modified Copernicus Sentinel-2 (Level 1C data processed into a surface reflectance product (Level 2)). Defra and JNCC data were processed on separate platforms using a common specification to produce complementary outputs. The majority of data captured between July 2015 and August 2017 was processed by Aberystwyth University for Defra and later updated by JNCC to the same specification as the rest of this dataset. Please see the image-level metadata for details of data lineage and processing.

  • Earth-system modelling data from the UK-Japan Climate Collaboration (UJCC). The project is a joint project between the Hadley Centre (DEFRA) and the NCAS-CGAM (Centre for Global Atmospheric Modelling) at the University of Reading. UJCC makes use of a broad group of models in order to systematically explore the role and value of resolution in climate system research. The dataset comprises of UJCC 30 year simulations from models at resolutions of either (1.25 lat x 1.875 lon) or (0.83 lat x 1.25 lon) with differing degrees of atmosphere-ocean coupling (1 degree ocean or 1/3 degree ocean). The dataset also includes NUGAM (Nihon-UK Global Environmental Model) Atmosphere only simulations and NUGEM Coupled atmosphere and ocean simulations which are both at the same resolution (0.83 lat x 0.56 lon, corresponding to ~60 km in mid-latitudes).

  • The UK Climate Impacts Programme 2002 (UKCIP02) comprises a set of four scenarios of future climate change produced for assessing climate change vulnerability, impacts and adaptation in the UK based on the understanding of the science of climate change in 2002. Data are provided at two resolutions 50km and 5km. The 5km resolution data are provided in both a gridded and time-series format. The four alternative future climates for the UK are labelled respectively, Low Emissions, Medium-Low Emissions, Medium-High Emissions and High Emissions. No probabilities can be attached to these four climate futures – in line with the IPCC, UKCIP02 do not suggest that one is more likely than another. While they represent a wide range of possible future climates, the UKCIP02 scenarios do not capture the entire range of future possibilities. The scenarios are designed to be used in conjunction with other UKCIP reports and products.
