Have the results from Climateprediction.net been incorporated into UKCP09?
No, CP.net projections are not incorporated into UKCP09
In detail
Climateprediction.net (CP.net) is a distributed computing experiment
that uses the combined power of many home PCs to run thousands of
versions of the Met Office Hadley Centre HadCM3 global climate model.
Although CP.net uses a similar concept of multiple runs of many variants of a climate model, and uses the same global climate model as
a base, there are several important differences between the CP.net and
UKCP09 methodologies which mean the results are not directly
comparable. These include:
1) The CP.net experiments focus
mainly on a global scale, producing thousands of results for global
climate as a whole. UKCP09, although based around a large ensemble of global climate model results, downscales these to 25 km to explore changes specifically in the climate of the UK.
2) The CP.net experiments involve a much larger number of model runs
(thousands) than UKCP09 (initial ensemble of ~300). UKCP09 then uses a
technique called emulation to predict statistically what the results of a much larger ensemble (with about a million members) would be.
3) The UKCP09 results incorporate the results from single model runs of other IPCC global climate models. Other climate models have not, to date, been considered in the CP.net experiment.
4) CP.net doesn't save daily data
5) CP.net doesn't save the data that the UKCP09 methodology uses to weight different model versions.
