In V1 they made an explicit adjustment for UHI, which turned out to be rather small. V2 relies on changepoint detection.<br />Nick Stokeshttps://www.blogger.com/profile/06377413236983002873noreply@blogger.comtag:blogger.com,1999:blog-7729093380675162051.post-3149425546921228752014-06-07T08:23:30.728+10:002014-06-07T08:23:30.728+10:00Where, or how does UHI play into the temperatures?...Where, or how does UHI play into the temperatures?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7729093380675162051.post-4479441326810564222014-06-07T06:36:41.368+10:002014-06-07T06:36:41.368+10:00Yes, I stuck mainly with trying to get the actual ...Yes, I stuck mainly with trying to get the actual effect of adjustment. It isn't clear what Goggard is calculating, but I think you are probably right. In my notation it would be F2-F1, where F2 is average infilled. I've plotted q*(F2-F1), where q is the proportion infilled. Without the q it is noisy, because S2 (F2) often has very few members.Nick Stokeshttps://www.blogger.com/profile/06377413236983002873noreply@blogger.comtag:blogger.com,1999:blog-7729093380675162051.post-29123073120377664412014-06-07T00:18:04.763+10:002014-06-07T00:18:04.763+10:00My numbers were homogenized (infilled) - homogeniz...My numbers were homogenized (infilled) - homogenized (non-infilled), which likely accounts for much of the difference. I was unclear if Goddard was conflating homogenization and infilling or not, and wanted to focus on the latter.Zekehttps://www.blogger.com/profile/09757819498566612533noreply@blogger.com
