CA reader and contributor Neal J. King got a bevy of questions answered related to the June 14th posting of Parker 2006: An Urban Myth? and they are posted here in order. Thanks to Neal and Dr. Parker for making this available to all for reading and consideration. – Anthony Questions to Parker, Part 1: […]
Anthony Watts writes in about 4 more USHCN stations:
Today, I’d like to discuss an interesting problem raised recently by Joe d’Aleo here – has the temperature of New York City increased in the past 50 years? Figure 1 below is excerpted from their note, about which they observed. Note the adjustment was a significant one (a cooling exceeding 6 degrees from the mid […]
In browsing AR4 chapter 3, I encountered something that seems very strange in Table 3.2 which reports trends and trend significance for a variety of prominent temperature series (HAdCRU, HadSST, CRUTem). The caption states: The Durbin Watson D-statistic (not shown) for the residuals, after allowing for first-order serial correlation, never indicates significant positive serial correlation. […]
Gavin Schmidt recently told Anthony Watts that worrying about station data quality was soooo last year. His position was a bit hard to follow but it seemed to be more or less as follows: that GISS didn’t use station data, but in the alternative, as defence lawyers like to say, if GISS did use station […]
Gavin Schmidt has told Anthony Watts that the problematic station data are not used in climate models and any suggestion to the contrary is, in realclimate terminology, “just plain wrong”. If station data is not used to validate climate models, then what is? His point seems to be that the climate models use gridded data. […]
Today’s tide at surfacestations.org brought in an eastern site,Stamford Ct, courtesy of Kevin Green. A couple of interesting features, including something really weird with the GISS adjustments.
surfacestations.org is back online and there are some good improvements in layout. In the page directory for each state, there are now thumbnails for the stations with information. New stations are coming in all the time. Today’s tide brought in another interesting Washington site from Gary Kobes – Long Beach WA (454748; 72791002). Its physical […]
Russ Steele, who’s been working closely with Anthony Watts and who also deserves much credit for this recent initiative, reports on Ukiah CA at his blog here Ukiah is in the same gridcell as Petaluma. Russ shows a picture of the weather station which is on grass – there’s a tree nearby, but no incinerators, […]
Check out Petaluma CA at Anthony Watts’ blog. Anthony has shown the GISS unadjusted temperature graphic. In this case, the GISS raw data appears to be mostly the same as USHCN adjusted (filnet) up to different rounding; a few isolated values available in USHCN are missing in GISS raw for some strange reason. I’m starting […]
