Off-topic, but ... Anthon...Yes, that makes sense. <br /><br />Off-topic, but ... Anthony's post about Cowtan et al. 2015 for some reason includes a graph showing model-vs-data comparisons, not for the surface (as in the paper) but for the "tropical troposphere hotspot". This reminded me that there have been a variety of developments in recent months that seem to just appear and then sink without a trace.<br /><br />* Po-Chedley et al. 2015 seemed to present an improved processing method for MSU Middle Troposphere temperatures, which had much higher trends than UAH-TMT and went a long way towards "solving" the trop-trop hotspot issue. But almost nobody discussed it and the usual suspects continue to talk about this "missing hotspot".<br /><br />* In a post a few months back, Tamino showed graphs of radiosonde temperature data for the troposphere that look nothing at all like the graphs that S&C or Watts keep posting. What's up with that?<br /><br />I'm glad to see Cowtan et al. making improvements in model-data comparisons for the surface, but it'd be great if somebody were to bring that level of attention to the mid-troposphere model-data comparison problem. Are there ways in which those comparisons have been done badly in the past, analogous to what Cowtan et al. are describing for the surface? <br /><br />I have no particular point here, just vague stuff that's been on my mind lately.Ned Wnoreply@blogger.comtag:blogger.com,1999:blog-7729093380675162051.post-43288647599827021482015-07-31T11:28:22.847+10:002015-07-31T11:28:22.847+10:00Ned,

I think it is because NCEP reports air temp, and basically the bottom grid cell - so about 40 m altitude at center. The surface indices use SST over ocean. Lately SST's have been rising, while land temps have been mixed. I think NCEP may be lagging SST rise.<br /><br />This fits with the new paper of Cowtan et al, which I'll probably be writing about.<br />Nick Stokeshttps://www.blogger.com/profile/06377413236983002873noreply@blogger.comtag:blogger.com,1999:blog-7729093380675162051.post-32778703885693173802015-07-31T10:38:55.588+10:002015-07-31T10:38:55.588+10:00Thank you!

So ... July 2015 look...Thank you! That was quick.<br /><br />So ... July 2015 looks a lot like July 2014, according to NCEP/NCAR.Ned Wnoreply@blogger.comtag:blogger.com,1999:blog-7729093380675162051.post-82419968327598440262015-07-31T06:01:10.732+10:002015-07-31T06:01:10.732+10:00Thanks, Ned, yes that was a problem associated wit...Thanks, Ned, yes that was a problem associated with the new scheme.
