This has been commented on before I think. I also wonder if the UAH measurements have actually peaked, or will they go up again?Anonymoushttps://www.blogger.com/profile/11552461190113661645noreply@blogger.comtag:blogger.com,1999:blog-28837843.post-30989338695760411212016-07-07T11:09:22.457-07:002016-07-07T11:09:22.457-07:00Are they using different instruments in V6.5 vs V5...Are they using different instruments in V6.5 vs V5.6? The discrepancy between satellite and land measurements is small in 5.6 but quite large in 6.5. If the instruments are the same between versions then the change must be related to how the data is being processed. I'm not quite sure what issue version 6 was meant to address. I guess we'll have to wait for the paper?Layzejhttps://www.blogger.com/profile/11346550512734519728noreply@blogger.comtag:blogger.com,1999:blog-28837843.post-48274852194762870242016-07-07T01:53:21.222-07:002016-07-07T01:53:21.222-07:00Before 2000 UAH is reading warmer than GISS. 2000-...Before 2000 UAH is reading warmer than GISS. 2000-2005 the two are in agreement. 2005 onwards UAH is reading cooler than GISS, apart from the peak in 2011. Possible explanation is either a deterioration in the sensitivity of the satellite sensors, or an increase in the sensitivity of the GISS data collectors. The former seems more likely, because there are more surface temperature sensors than satellites.DocRichardhttps://www.blogger.com/profile/08903964792092284406noreply@blogger.comtag:blogger.com,1999:blog-28837843.post-28157947991023583582016-07-06T18:04:33.364-07:002016-07-06T18:04:33.364-07:00Good idea.

If you detrend both GISS and UAH6 you will still see as a general feature that UAH is quite a bit higher than GISS during El Nino and quite a bit lower during La Nina. Not so for this year though.Layzejhttps://www.blogger.com/profile/11346550512734519728noreply@blogger.com
