Climate change projections
Monthly/ seasonal/ annual2010 to 2099 as overlapping 30-year time periods 25 km grid over land only plus administrative regions and river basinsLow, Medium and HighMet Office Hadley Centre + other IPCC modelsNoYes
Other information: Also available for absolute future climate for some variables
Marine & coastal projections
Monthly/ seasonal/ annual2010 to 2099 as overlapping 30-year time periodsMarine regions Low, Medium and HighMet Office Hadley Centre + other IPCC modelsNoYes
Sea level projections
Annual1990 to 2100 as annual averagesUK as a whole and at user-specified locations around the coastLow, Medium and High and H++ mean SLR scenarioProjections for UK waters from IPCC global climate models and H++ from literature on constraintsYesNo, but there is an estimate of uncertainty based on frequency distributions
Other information: Absolute sea level for UK as a whole.  Relative sea level for all 12 km native grid squares.  H++ scenario described in report
Storm surge height projections
Trend in return periods1960 to 2100 long term trend12 km grid squares around UK coastlineMedium and H++ scenarioMet Office Hadley Centre regional climate model used to run POLCS3 storm surge modelYesNo, but there is an estimate of uncertainty based on frequency distributions
Multi-level ocean projections
Monthly/ seasonal/ annual1961 to 1990 and 2070 to 2099 as 30-year time periods 12 km grid squares and
2 vertical levels (water surface and sea-bed)
