UKCP09 25 km grid

The 25 km resolution grid on which the UKCP09 probabilistic climate projections are available.

In detail

The HadRM3 has been used to downscale the global climate simulations to a spatial resolution better suited to that which has meaning in terms of impacts and adaptation assessments. This RCM operates at 25 km resolution.

The UKCP09 25 km grid has a rotated pole meaning that the grid orientation appears to be rotated anti-clockwise relative to true north. Each grid square is approximately 25 km x 25 km in size and is either assigned as land or sea. In total there are 434 land grid squares that define the UK and for which probabilistic climate projections are available.

  • The UKCP09 25 km grid is displayed in Figure 7 of the UKCP09 Briefing report.
  • Projections are provided for every 25 km grid square. A single grid square location is one of the elements that can be specified when building a request in the UKCP09 User Interface.
  • Part of the UKCP09 methodology is consideration of the baseline 1961-1990 climate observational data which is also available at 25 km resolution.
