Parker 2006: An Urban Myth?

If you are not a climate scientist (or a realclimate reader), you would almost certainly believe, from your own experience, that cities are warmer than the surrounding countryside – the “urban heat island”. From that, it’s easy to conclude that as cities become bigger and as towns become cities and villages become towns, that there […]

Some Prompt Data Responses

A couple of prompt and favorable responses to inquiries for data from Parker 2006 and Nyberg et al 2007 (a recent article on hurricanes) Parker 2006 I wrote Parker today inquiring about the sites used in Parker 2006 and for data for unarchived sites. He replied promptly as follows: Here are the station lists. The […]

Latex Matters

Anthony Watts reports on whitewash versus latex.

The Minnesota Dam Nation

I pointed out the hot spot in northern Minnesota in the contoured USHCN trends. There was a really interesting discussion of Minnesota sites by their state climatologist, JAmes Zandlo, in 2000, a couple of years ahead of Roger Pielke Sr’s investigations in Colorado. He showed the following contour for Minnesota (which prompted me to do […]

B-44 Forms

Russell S. Vose, David R. Easterling, Thomas R. Karl, and Michael Helfert, Comments on “Microclimate Exposures of Surface-Based Weather Stations”, BAMS, 2005 stated: “Cooperative Station Reports (i.e., B-44 forms) are available online from the National Climatic Data Center.” I spent quite a bit of time searching for B-rr forms. I tried Dale Kaiser of CDIAC, […]

The T3 Tax

I try to stay away from policy discussions here (although others sneak it in), but this suggestion by Ross McKitrick is so ingenious that I’ll relax my policy for a while. Ross proposes a carbon tax linked to tropical troposphere temperatures – the fingerprint of the CO2 contribution to warming. If models are wrong and […]

Hansen Red and Blue States

I did plots for both GISS station data and GISS gridcell data on the same basis as USHCN.

USHCN Trends: Red States and Blue States

I’ve calculated the trends for all 1221 USHCN stations after 1900 and plotted up the contour maps for the raw, time-of-observation adjusted and fully adjusted results. Pretty interesting results. Here’s the results for the “raw” data, the adjusted versions are shown below. Contour map of 20th century trends for 1221 USHCN stations – “raw” data. […]

Mannomatic Smoothing and Pinned End-points

We’ve had a couple of discussions of dealing with end-points for smoothing. Here’s a little note about smoothing algorithms, which I think is pretty funny. It’s hard to imagine a note about smoothing algorithms being funny, but see what you think.

Three "New" Sites from Anthony Watts

Anthony Watts has three new sites: Lovelock, Electra and Fallon, and there’s something unexpected in them (Aside from the jet fighter discharging on the weather station – which is disappointing but almost expected by now.)
