For Roman M, You asked about the URL I gave. Answer, I don’t know. There was a glitch, probably with the IP assignment. I have never seen
http://www.pbjmgt.co.uk/ before.

The primary URL is http://cdiac.ornl.gov/ftp/ndp020/

This gives a number of stations with Phil Jones temperature data, e.g.

jonesnh.dat 24-Jun-1993 17:04 8.2MB
jonessh.dat 24-Jun-1993 17:04 1.2MB

Plus about a 30 other files, some of which are code. Resembles the working sheets in preparing a paper.

In the NH file, just a few random USA stations are (WMO number also given)
BIG DELTA
GULKANA
ANCHORAGE
MATANUSKA/EXP
VALDEZ
EAGLE
NORTHWAY AIRPORT
CORDOVA
ST.PAUL

These seem to be the sources of one of the Jones papers and I posted them on CA in case people wanted to capture at least some Jones data
before it all disappeared. I was trying to find which paper used this info.

I have plotted several long term stations in Australia from 1870s to now, annual averages from BOM early, BOM later CD, BOM current online, Giss homogenised, KNMI/GHCN, and now, for some stations where given above, the CRU version to year 1991. This is the first time I have found actual station data from CRU and it is monthly. The spaghetti graphs are all over the place, with spreads of several degrees C in a given year being common. The aim is to track down the most credible master version then place weights or pass/fail on later adjustments of the master.

There is so much data floating around that it’s hard to keep track of prevenance and publication. Some of it it so bad it would be misleading if used by an innocent trying to explain why earth temp varies.

My apologies. I did not try to waste your time.

The editorial notes say that the identification numbers in the WWR book bear no relationship to the WMO international index numbers, but this must be the data that Dr. Jones used for early papers–how much different data could there have been between 1921-1950 for Jan Mayen?

Other interesting things I’ve noticed in the book; there have already been numerous adjustments done to the data, several different formulas have been used to arrive at the means(maybe this is common even now, I don’t know), many stations contain multiple moves where the records have been harmonically smoothed, corrections have been applied for different types of shelters(in the tropics apparently they used thatched roof shelters sometimes on verandas), and each volume seems to contain extensive errata tables where errors have been noticed for previous volumes. It would be interesting to know if all of this was taken into account when they were digitized. Anyways this may be stuff you already knew–hope I’m not wasting your bandwidth.

GHCN distributing what appears to be the same data may not be in violation of their license agreement with Environment Canada. It certainly is odd that one can acquire the data without fee or restriction from GHCN, but if you want it from EC you are subject to the license agreement. One assumes of course that the data that EC is providing is in fact subject to Canadian copyright law. In the US data is not subject to copyright as it is not a creative expression. Anyhoo, I don’t mean to take this thread off topic, as Steve has made it clear that he doesn’t want his blog littered with those arguments. I just find it curious. Back to my original point, one would presume that GHCN has a seperate agreement with EC such that the data can be redistributed without violation.

Ed, from examining the site, the data is for the “historically adjusted temperature data”, so it is not the raw feed (http://www.cccma.bc.ec.gc.ca/hccd/data/temperature/tempdata.shtml). But based upon their copyright page, the use to which you wish to use the data would be allowed as long as you follow their guidelines.

Based upon their stations list (http://www.cccma.bc.ec.gc.ca/hccd/data/temperature/temperature_stations.txt), most of the data runs through the early 2000′s. Only problem I see is that you only get to access the data one station at a time.

I went looking for the missing Canadian data. I didn’t find the missing data; but guess what I did find: a license agreement on Canadian temperature data that would prevent it from being released as part of either the CRU or GHCN dataset!

Here’s the dataset: http://www.cccma.ec.gc.ca/hccd/

Here’s the license: http://www.cccma.ec.gc.ca/hccd/license.shtml

The license specificly prohibits distribution of the data except for “educational or research purposes for which you have received explicit written permission from Environment Canada”.

Ironically, GHCN seems to contain this data already, and seems to publish it without restrictions in a manner that clearly violates the terms of the Environment Canada license. There are about 200 Canadian series that continue past 1990 in GHCN (the same as the dataset on the Environment Canada website. I’ve applied for a license to download the data, and will let you know whether the stations are contained in this product are those that are contained in GHCN V2. I strongly suspect that they are. (Letting you know whether the data is the same does not appear to be prohibited by the terms of the license).
