Arctic Temperature Data From CLIMAS
February 14, 2015

The CLIMAS (Climate information access system) was set up to provide climate data for high latitudes, although it does not seem to have been updated since 2000.

The project was a joint effort from, amongst others, the Max Planck Institute, Nansen Environmental and Remote Sensing Center and St Petersburg University.

The data they provide includes monthly temperature data from 28 weather stations around the Arctic. Checks at Jan Mayen Island and Nuuk confirm that these tally with the raw GHCN Version 2 data, which I used in my earlier analysis.

For instance, Jan Mayen.

GISS Version 2

Now compare with the new adjusted version at GISS.



GISS Version 3

The new GISS temperatures all 1.1C cooler than the CLIMAS set for 1924/5.


The CLIMAS system also gives graphing. (Bear in mind this only runs to 2000).

Just taking three at random, Godthaab Nuuk (Greenland), Jan Mayen (Norway) and Akureyri (Iceland).

All show the 1940’s spike, at least as high as anything prior to 2000. They also show the big cooling in the 1960’s and 70’s, but, in addition, they show other abrupt changes, such as the big ups and downs around 1940. Such rapid changes in the Arctic are well known to specialists in this field.







Now compare with the current GISS version of the temperature record.

The CLIMAS temperature database, which was created by the Arctic & Antarctic Research Insitute in St Petersburg, is apparently good enough for Arctic climate research but not good enough for GISS.
