I noticed something interesting in AR4 about Antarctic models, that no one mentioned in the initial commentary on Steig et al. When Steig et al 2009 came out, commenters had some fun teasing the clergy over at realclimate over Spencer Weart’s article the prior year. Pielke Jr Lucia CA Speaking for myself, I went to [...]
Beckers and Rixen 2003 url is an interesting read in two respects: 1) they present a non-RegEM infilling approach. The method appears to be exactly the same as one that I (independently) implemented and illustrated about a month ago – what I termed “truncated PC”. This was actually the very first thing that I did [...]
There has been a good deal of discussion regarding the correlation between temperatures at various locations throughout Antarctica. Several people have looked at the relationship between correlation and distance by creating graphs linking the two. IMO, one of the difficulties in interpreting these is that they are affected by a variety of factors, including the [...]
The Jeffs have been exploring the UWisc AVHRR data which is stored as a lot of gzipped ncdf files. I couldn’t figure out how to download and open this data into R. So, as I usually do in these cases, I asked CA reader Nicholas who, as usual, has a solution. I edited this slightly [...]
Update Mar 28: Here is Luboš version replacing my much less pretty monochrome version showing the spatial decorrelation of the “Comiso” version of the data recently archived a couple of days ago by Steig. Figure 1. Spatial Correlation for Sample of “Comiso 2009″ Antarctic Gridcells Jeff Id has compared this to corresponding surface stations at [...]
I checked in at Steig’s webpage to see if the long-awaited AVHRR had finally materialized. Update (Mar 26, 2009 aa am Eastern) This is now released. It had the following new paragraph (without any change notice to show that this dataset had not been there from time immemorial): cloudmaskedAVHRR.txt contains the monthly-averaged cloud-masked satellite data [...]
A couple of months ago, as I mentioned at the time, Ross and I submitted a paper to International Journal of Climatology discussing Santer, Schmidt et al versus Douglass et al. I just checked the status of the submission at the journal website and learned that the submission is subject to a “Special Decision”. We [...]
Back in Toronto after two weeks in Thailand. One of my sons got married and my wife and I spent time traveling with my son and new daughter-in-law and my daughter. I left New York on Monday Mar 9 back to Toronto and left the next morning for Thailand, pretty groggy when I arrived on [...]
I’ve lost track of the number of “unthreadeds” on CA, but the last one at 800 + posts is getting a bit unwieldy. So please continue here. – Anthony
