>SST Reconstructions

>INTRODUCTION

The NCDC webpage for the World Data Center for Paleoclimatology provides access to data sets for reconstructions of a number of variables. Refer to:
http://www.ncdc.noaa.gov/paleo/recons.html

Since I’ve been on an SST kick recently, I decided to download their SST reconstructions that were relatively short term, no longer than 1,000 years, but at least 250 years. I excluded one data set due to the limited number of data points and the sporadic spacing of those readings.

The surprise: There was no hockey stick. Not one. All of the data sets appeared to reflect the real world.

In the following, I provided titles, data citations, links to the data and, where separate, links to the descriptions. For the Indo-Pacific Warm Pool, I also provided ERSST data as a reference to current SST, Figure 4. And for the North Atlantic, since the temperature swings appeared too large, I also provided a comparison to ERSST data, Figure 7. Other than that, the graphs will speak for themselves.

In Figure 3, I shifted the graph scale to cut off much of the spike at 1463 to emphasize the other data. Figure 4 is ERSST.v2 data for the Pacific Warm Pool from 1854 to 2007 that I provided as a reference.

    >Just found this post from WUWT. What's with the giant spike in some of the graphs?

  2. Bob Tisdale says:

    >Greg: Sorry, I haven’t the slightest idea about the spikes. You’ll have to refer to the respective papers:For Figure 1, Black et al, An 8-century tropical Atlantic SST record from the Cariaco Basin: Baseline variability, twentieth-century warming, and Atlantic hurricane frequency:http://www.agu.org/pubs/crossref/2007/2007PA001427.shtmlFor Figure 2, Newton et al, Climate and hydrographic variability in the Indo-Pacific Warm Pool during the last millennium:http://www.agu.org/pubs/crossref/2006/2006GL027234.shtmlFor Figure 6, Gray et al, A tree-ring based reconstruction of the Atlantic MultidecadalOscillation since 1567 A.D.:http://wwwpaztcn.wr.usgs.gov/julio_pdf/Gray_ea_AMO.pdf
