GHCC (noted as UAH MSU) a.k.a. 'satellite' measures current series LT5.2 |
Global Hydrology and Climate Center, University of Alabama - Huntsville, USA
The data used were obtained by the National Oceanographic and Atmospheric Administration TIROS-N satellite, and interpreted by scientists Dr. Roy Spencer (University of Alabama at Huntsville) and Dr. John Christy (University of Alabama at Huntsville) at the Global Hydrology and Climate Center (GHCC), a cooperative laboratory involving NASA, the Alabama Space Science and Technology Alliance, and private industry. A brief outline of Globally-Averaged Atmospheric Temperatures may be found here. Monthly means of the lower troposphere (LTv5.2) here and zonal data here. CSV files: Global; Zonal-all regions (does not distinguish between land/water); United States (48); Tropics; Northern Hemisphere; Northern Extratropics; Northern Polar; Southern Hemisphere; Southern Extratropics; Southern Polar and, just in case one file is updated before the other, here's another Global, this time derived from the zonal file.

| Hadley |
The Hadley Centre for Climate Prediction and Research, which is part of the Met Office, provides a focus in the United Kingdom for the scientific issues associated with climate change. From Hadley we have the Central England Temperature track dating from 1659. 1659-1973 MANLEY (Q.J.R.METEOROL.SOC., 1974) 1974-ON PARKER ET AL. (INT.J.CLIM., 1992) CSV files: Monthly; Annual

| HadAT2 |
HadAT: globally gridded radiosonde temperature anomalies from 1958 to present HadAT is the Hadley Centre's new radiosonde temperature product. It supersedes HadRT which will continue to be made available in parallel for a short while. This website contains a full audit trail of all the decisions made in the construction of HadAT, a range of fully gridded and globally / regionally averaged products on a monthly or seasonal resolution, and some frequently used graphics. When using HadAT the correct citation is: Thorne, P. W., Parker, D. E., Tett, S. F. B., Jones, P. D., McCarthy, M., Coleman, H., and Brohan, P., 2005, Revisiting radiosonde upper-air temperatures from 1958 to 2002, J. Geophys. Res., 110, D18105, doi:10.1029/2004JD005753. As an absolute minimum requirement for correct usage it is imperative that users read and understand this paper.

| NCDC |
National Climatic Data Center produces global land and ocean surface temperature anomalies and an absolute global mean temperature set (others here). These time series are calculated using land surface data from the Global Historical Climatology Network (Version 2) and sea surface temperature anomalies from the United Kingdom MOHSST data set and the NCEP Optimum Interpolated SSTs (Version2). Small differences in anomalies for previous years may occur from time to time due to the addition of recently collected station data or the incorporation of more recent versions of the base data sets.
*In February, 2006 NCDC transitioned to the use of an improved Global Land and Ocean data set (Smith and Reynolds analysis (2005)) which incorporates new algorithms that better account for factors such as changes in spatial coverage and evolving observing methods. (See NCDC Global Surface Temperature Anomalies) The same file states "The global monthly surface temperature averages in the table below can be added to a given month's anomaly (departure from the 1880 to 2004 base period average) to obtain an absolute estimate of surface temperature for that month."
The following are references that can be used when citing GHCN and/or provide additional information on the data set:
CSV files: Absolute Mean; Mean Anomaly; Land Mean; Ocean Mean; Land Anomaly; Ocean Anomaly.
