date: Thu, 21 May 2009 09:18:58 +0100 from: "Colin Harpham" subject: SCORCHIO cfs to: "Clare Goodess" , "Phil Jones" Clare/Phil, If we were to use a different baseline to calculate the cfs in order to inflate the scenario for the central UHI cell could we justify it? Looking at it from an outsiders perspective I would ask the following questions: 1) Why has a different baseline been used to calculate the cfs, does this imply that the 1971-1990 period (for e.g. Urb3Anth) does not reflect observed climate? 2) If the baseline period is incorrect then can we have confidence in the WG scenario produced? 3) UrbAnth - noUrbnoAnth has been used to calculate cfs for an urban cell when we know from observed data that cell already contains urban and anthropogenic influences for 1971-1990. Or something along those lines... Opinions? Once I have finished the UKCP09 testing I'll calculate the cfs for UrbAnth - noUrbnoAnth and Urb3Anth - noUrbnoAnth to see what the numbers actually look like. Cheers Colin
