There are three main global temperature histories: the combined CRU-Hadley record (HADCRU), the NASA-GISS (GISTEMP) record, and the NOAA record. All three global averages depend on the same underlying land data archive, the Global Historical Climatology Network (GHCN). Because of this reliance on GHCN, its quality deficiencies will constrain the quality of all derived products. The number of weather stations providing data to GHCN plunged in 1990 and again in 2005. The sample size has fallen by… Expand
Urbanization bias III. Estimating the extent of bias in the Historical Climatology Network datasets
The extent to which two widely-used monthly temperature datasets are aected by urbanization bias was considered. These were the Global Historical Climatology Network (GHCN) and the United StatesExpand
An audit of uncertainties in the HadCRUT4 temperature anomaly dataset plus the investigation of three other contemporary climate issues
This thesis is in two parts. The first discusses many uncertainties associated with the widely used HadCRUT4 global temperature dataset. The second part deals with three other issues in climateExpand
Possible Impact of Spatial and Temporal Non-Uniformity in Land Surface Temperature Data on Trend Estimation
The present work investigates possible impact of the non-uniformity in observed land surface temperature on trend estimation, based on Climatic Research Unit (CRU) Temperature Version 4 (CRUTEM4)Expand
Sustainable Infrastructure: Climate Changes and Carbon Dioxide
Civil infrastructure provides the physical backbone of all societies. Water supply, wastewater treatment, transportation systems, and civil structures must be sustainable over multiple decades (e.g.Expand


Hemispheric and Large-Scale Surface Air Temperature Variations: An Extensive Revision and an Update to 2001.
This study is an extensive revision of the Climatic Research Unit (CRU) land station temperature database that is used to produce a gridbox dataset of 58 latitude 3 58 longitude temperatureExpand
Global trends of measured surface air temperature
We analyze surface air temperature data from available meteorological stations with principal focus on the period 1880–1985. The temperature changes at mid- and high latitude stations separated byExpand
GISS analysis of surface temperature change
We describe the current GISS analysis of surface temperature change for the period 1880-1999 based primarily on meteorological station measurements. The global surface temperature in 1998 was theExpand
An Overview of the Global Historical Climatology Network Temperature Database
Abstract The Global Historical Climatology Network version 2 temperature database was released in May 1997. This century-scale dataset consists of monthly surface observations from ∼7000 stationsExpand
Global historical climatology network (GHCN) quality control of monthly temperature data
In producing version 2 of the global historical climatology network's (GHCN) temperature data sets, a variety of quality control tests were evaluated and a specialized suite of procedures was developed. Expand
The evolving SST record from ICOADS
Sea surface temperature (SST) is a key oceanic variable – widely used for research, including global climate change assessments and atmospheric reanalyses. This paper reviews the evolution of the SSTExpand
Uncertainty estimates in regional and global observed temperature changes: A new data set from 1850
[1] The historical surface temperature data set HadCRUT provides a record of surface temperature trends and variability since 1850. A new version of this data set, HadCRUT3, has been produced,Expand
Improvements to NOAA’s Historical Merged Land–Ocean Surface Temperature Analysis (1880–2006)
Abstract Observations of sea surface and land–near-surface merged temperature anomalies are used to monitor climate variations and to evaluate climate simulations; therefore, it is important to makeExpand
The Global Historical Climatology Network: Long-term monthly temperature, precipitation, sea level pressure, and station pressure data
Interest in global climate change has risen dramatically during the last several years. In a similar fashion, the number of data sets available to study global change has also increased.Expand
Global analyses of sea surface temperature, sea ice, and night marine air temperature since the late nineteenth century
[1] We present the Met Office Hadley Centre's sea ice and sea surface temperature (SST) data set, HadISST1, and the nighttime marine air temperature (NMAT) data set, HadMAT1. HadISST1 replaces theExpand
