Why the difference?

Here is a puzzling comparison of two zonal averages from Phil Jones’ CRUTEM3 gridded land data. Red shows the average from 20S to 20N and black shows the average of the 20-30S band (both N and S). These are calculated from gridded data at http://hadobs.metoffice.com/crutem3/data/CRUTEM3.nc. I did this comparison because I noticed a difference between […]

UK Met Office: Refuse and Delete

A couple of week ago, I noticed that the UK Met Office website contained the following statement Q. Where can I get the raw observations? A. The raw sea-surface temperature observations used to create HadSST2 are taken from ICOADS (International Comprehensive Ocean Atmosphere Data Set). These can be found at icoads.noaa.gov/. To obtain the archive […]

Another Try on the Wall

CA readers are well aware that Phil Jones of CRU has jealously refused to provide the surface temperature data set used in the prominent HadCRU temperature index, going so far as to repudiate Freedom of Information requests. Efforts to obtain this data have been chronicled here from time to time. As a result of the […]

Emulating CRUTem Graphics

Because of the puzzles in trying to replicate the NOAA graphic from archived data, I’ve also tried to replicate the HadCRU plots from archived data. Hu McCulloch has criticized the highly inappropriate use of Mercator projections by climate scientists and, as an exercise, I figured out a fairly simple method of plotting these results in […]

CRUTEM and HadCRU October 2008

Released today on the promised schedule are CRUTEM3 and HadCRUT3 for October 2008. October 2008 was in the top 8 crutem3 (0.517 deg C)and in the top 6 hadcru3 (0.440 deg C) Octobers. Because our collective eyes right now are fairly attuned to the colors of these grids and how changes in individual stations affect […]

A First Look at the CRU Station List

On Sept 28, 2006, Willis Eschenbach sent an FOI for CRU station data. A year later, after many letters, we still do not have the CRU data as used, but do have a list of stations used, a list which is slightly shorter (4138) than the 4349 stations said to have been used in Brohan […]

CRU Reveals Station Identities

Willis Eschenbach received a message today that the CRU list of stations used is online at http://www.cru.uea.ac.uk/cru/data/landstations/ . The webpage says: The file gives the locations and names of the 4138 stations used at some time (i.e. in the gridding that is used to produce CRUTEM3) during the period from 1851 to 2006. All these […]

Some Gridcell and Station Utilities

I’ve posted up a collection of functions to read from various gridcell and station archives into organized time series objects here. Read functions are included for HadCRUT3, HAdCRUT2, GISS gridded, GHCN v2, GISS station, GSN, meteo.ru, unaami and G02141. I’ll probably add to this from time to time now that I’ve figured out an organization […]

Barabinsk, Russia 57N, 77E

I’ve been going through the process of reconciling gridded data and station data in one Russian gridcell. Most of my effort to date has been spent on creating tools for accessing and collating data archives into organized time series formats so that others don’t have to go through the same trials and tribulations of sorting […]

We Have 25 Years Invested in This Work…

Some of you may recall the memorable climate science phrase: We have 25 or so years invested in the work. Why should I make the data available to you, when your aim is to try and find something wrong with it. Here’s the story behind this and some updates on it.
