Uncertainty estimates in regional and global observed temperature changes: A new data set from 1850
TL;DR: HadCRUT3 as mentioned in this paper is a new version of this data set, benefiting from recent improvements to the sea surface temperature data set which forms its marine component, and from improving to the station records which provide the land data.
Journal ArticleDOI
Quantifying uncertainties in global and regional temperature change using an ensemble of observational estimates: The HadCRUT4 data set
TL;DR: HadCRUT4 as mentioned in this paper is a new data set of global and regional temperature evolution from 1850 to the present, which includes the addition of newly digitized measurement data, both over land and sea, new sea-surface temperature bias adjustments and a more comprehensive error model for describing uncertainties in sea surface temperature measurements.
Journal ArticleDOI
Improved analyses of changes and uncertainties in sea surface temperature measured in Situ since the mid-nineteenth century: The HadSST2 dataset
Nick Rayner,Philip Brohan,David E. Parker,Chris K. Folland,John Kennedy,Michael Vanicek,T. J. Ansell,Simon F. B. Tett +7 more
TL;DR: The Second Hadley Centre Sea Surface Temperature dataset (HadSST2) as mentioned in this paper is based on data contained within the recently created International Comprehensive Ocean-Atmosphere Data Set (ICOADS) database and has smaller uncertainties.
Journal ArticleDOI
A Tripole Index for the Interdecadal Pacific Oscillation
Benjamin J. Henley,Joelle Gergis,David J. Karoly,Scott B. Power,John Kennedy,Chris K. Folland,Chris K. Folland +6 more
TL;DR: The Tripole Index (TPI) as discussed by the authors is a non-PC-based index for tracking decadal SST variability associated with the IPO, which is based on the difference between SST averaged over the central equatorial Pacific and the average of the SSTA in the Northwest and Southwest Pacific.
Journal ArticleDOI

TL;DR: The 20CRv2c dataset as mentioned in this paper is the first ensemble of sub-daily global atmospheric conditions spanning over 100 years, which provides a best estimate of the weather at any given place and time as well as an estimate of its confidence and uncertainty.
