The problem really is that it is refined on quality first, and then spatially. It would be better to do both simultaneously, being more tolerant of quality for isolated places.Nick Stokeshttps://www.blogger.com/profile/06377413236983002873noreply@blogger.comtag:blogger.com,1999:blog-7729093380675162051.post-37156380295659020432014-01-23T05:32:25.232+11:002014-01-23T05:32:25.232+11:00"But as you say, there are also critical stat..."But as you say, there are also critical stations that have been omitted, but would give better spatial coverage if included.

You can then vary this by including the xx most isolated stations to see if the concern actually has an effect.Kevin O'Neillhttps://www.blogger.com/profile/06692943768484857724noreply@blogger.comtag:blogger.com,1999:blog-7729093380675162051.post-41842113999780815392014-01-03T17:50:44.643+11:002014-01-03T17:50:44.643+11:00It's surprising that the criteria as stated do...It's surprising that the criteria as stated do not include a Hawaii station. At this stage I've mainly been concerned with merging quality and spatial criteria, without thinking too much about what the quality criteria should be. <br /><br />Probably the requirement of data after 2009 is too severe, though gently relaxing that would not add Hawaii stations. I think the rural designation has to be maintained.<br /><br />You've made a valuable point though. Partly the idea of reducing to a small number of stations is that they can then be carefully scrutinised for quality. But as you say, there are also critical stations that have been omitted, but would give better spatial coverage if included. It is not clear how to look at these systematically.<br />Nick Stokeshttps://www.blogger.com/profile/06377413236983002873noreply@blogger.comtag:blogger.com,1999:blog-7729093380675162051.post-28284243922909996022014-01-03T16:36:17.619+11:002014-01-03T16:36:17.619+11:00too bad the Lihue station location has wrong coord...too bad the Lihue station location has wrong coordinates, if we're to believe bing.maps and Berkeleley earth research being accurate. So the Hawaii station to be included would likely be Hilo, I guess in tropics the heating from the houses doesn't affect much.Oalehttps://www.blogger.com/profile/14032383453035968859noreply@blogger.comtag:blogger.com,1999:blog-7729093380675162051.post-46469253414626786482014-01-03T15:59:54.274+11:002014-01-03T15:59:54.274+11:00Moving the discussion here, the Berkeley earth res...Moving the discussion here, the Berkeley earth research for the two stations at Hawaii I talked about in the last post.<br />http://berkeleyearth.lbl.gov/stations/169971 <br />http://berkeleyearth.lbl.gov/stations/160281<br />Would still indicate that Lihue station has a better early record than Hilo (General Lyman Airport) station. There has possibly been more inaccurate in-terms reading the thermometer for the larger amount of rejected observations but the amount is still quite small, and the station location hasn't moved too much in the early record.Oalehttps://www.blogger.com/profile/14032383453035968859noreply@blogger.comtag:blogger.com,1999:blog-7729093380675162051.post-60254427293720462392014-01-03T07:16:27.672+11:002014-01-03T07:16:27.672+11:00Oale commented on an earlier post, saying among ot...Oale <a href="http://moyhu.blogspot.com/2013/12/november-giss-temp-up-by-017.html?showComment=1388663373087#c1785702336462203722" rel="nofollow">commented on an earlier post</a>, saying among other helpful things that the last plot had been covering the comments section.
