HadCRUT
HadCRUT is the dataset of worldwide monthly instrumental temperature records formed by combining the sea surface temperature records compiled by the Hadley Centre for Climate Prediction and Research, Hadley Centre of the UK Met Office and the land surface air temperature records compiled by the Climatic Research Unit, Climatic Research Unit (CRU) of the University of East Anglia. "HadCRUT" stands for Hadley Centre/Climatic Research Unit Temperature. The data is provided on a grid of boxes covering the globe, with values provided for only those boxes containing temperature observations in a particular month and year. Interpolation is not applied to infill missing values. The first version of HadCRUT initially spanned the period 1881–1993, and this was later extended to begin in 1850 and to be regularly updated to the current year/month in near real-time data, real-time. HadCRUT4 HadCRUT4 was introduced in March 2012. It "includes the addition of newly digitised measurement ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Climatic Research Unit
The Climatic Research Unit (CRU) is a component of the University of East Anglia and is one of the leading institutions concerned with the study of natural and anthropogenic climate change. With a staff of some thirty research scientists and students, the CRU has contributed to the development of a number of the data sets widely used in climate research, including one of the global temperature records used to monitor the state of the climate system, as well as statistical software packages and climate models. History The CRU was founded in 1972 as part of the university's School of Environmental sciences. The establishment of the Unit owed much to the support of Sir Graham Sutton, a former Director-General of the Meteorological Office, Lord Solly Zuckerman, an adviser to the University, and Professors Keith Clayton and Brian Funnel, Deans of the School of Environmental Sciences in 1971 and 1972. Initial sponsors included British Petroleum, the Nuffield Foundation and Roya ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Temperature Anomaly
Temperature anomaly is the difference, positive or negative, of a temperature from a base or reference value, normally chosen as an average of temperatures over a certain reference or base period. In atmospheric sciences, the average temperature is commonly calculated over a period of at least 30 years over a homogeneous geographic region, or globally over the entire planet. Temperatures are obtained from surface and offshore weather stations or inferred from meteorological satellite data. Temperature anomalies can be calculated based on datasets of near-surface and upper-air atmospheric temperatures or sea surface temperatures. Description Temperature anomalies are a measure of temperature compared to a reference temperature, which is often calculated as an average of temperatures over a reference period, often called a base period. Publication datePrecursor webpagewas archived as early as December 2013. Records of global average surface temperature are usually presented as ...

Instrumental Temperature Record
Global surface temperature (GST) is the average temperature of Earth's surface. More precisely, it is the weighted average of the temperatures over the ocean and land. The former is also called sea surface temperature and the latter is called surface air temperature. Temperature data comes mainly from weather stations and satellites. To estimate data in the distant past, proxy data can be used for example from tree rings, corals, and ice cores. Observing the rising GST over time is one of the many lines of evidence supporting the scientific consensus on climate change, which is that human activities are causing climate change. Alternative terms for the same thing are global mean surface temperature (GMST) or global average surface temperature. Series of reliable temperature measurements in some regions began in the 1850—1880 time frame (this is called the ''instrumental temperature record''). The longest-running temperature record is the Central England temperature d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freedom Of Information Requests To The Climatic Research Unit
Freedom of Information requests to the Climatic Research Unit featured in press discussions of disputes over access to data from instrumental temperature records, particularly during the Climatic Research Unit email controversy which began in November 2009. The UK Freedom of Information Act (FOIA) came into effect in 2005, and FOI requests were made to the Climatic Research Unit (CRU) at the University of East Anglia (UEA) for the raw data from weather stations used in developing instrumental temperature record datasets, for copies of agreements under which the raw data was obtained from meteorology institutions, and also for email correspondence relating to the Intergovernmental Panel on Climate Change Fourth Assessment Report. In many cases the raw data which CRU had obtained from National Meteorological Organisations was subject to restrictions on redistribution: on 12 August 2009 CRU announced that they were seeking permission to waive these restrictions, and on 24 November ...

Dataset
A data set (or dataset) is a collection of data. In the case of tabular data, a data set corresponds to one or more database tables, where every column of a table represents a particular variable, and each row corresponds to a given record of the data set in question. The data set lists values for each of the variables, such as for example height and weight of an object, for each member of the data set. Data sets can also consist of a collection of documents or files. In the open data discipline, a dataset is a unit used to measure the amount of information released in a public open data repository. The European data.europa.eu portal aggregates more than a million data sets. Properties Several characteristics define a data set's structure and properties. These include the number and types of the attributes or variables, and various statistical measures applicable to them, such as standard deviation and kurtosis. The values may be numbers, such as real numbers or integ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Climate And Weather Statistics
Climate is the long-term weather pattern in a region, typically averaged over 30 years. More rigorously, it is the mean and variability of meteorological variables over a time spanning from months to millions of years. Some of the meteorological variables that are commonly measured are temperature, humidity, atmospheric pressure, wind, and precipitation. In a broader sense, climate is the state of the components of the climate system, including the atmosphere, hydrosphere, cryosphere, lithosphere and biosphere and the interactions between them. The climate of a location is affected by its latitude, longitude, terrain, altitude, land use and nearby water bodies and their currents. Climates can be classified according to the average and typical variables, most commonly temperature and precipitation. The most widely used classification scheme is the Köppen climate classification. The Thornthwaite system, in use since 1948, incorporates evapotranspiration along with temperature ...

Freedom Of Information Act 2000
The Freedom of Information Act 2000 (c. 36) is an Act of the Parliament of the United Kingdom that creates a public right of access to information held by public authorities. It is the implementation of freedom of information legislation in the United Kingdom on a national level. Its application is limited in Scotland (which has its own freedom of information legislation) to UK Government offices located in Scotland. The Act implements a manifesto commitment of the Labour Party in the 1997 general election, developed by David Clark as a 1997 White Paper. The final version of the Act was criticised by freedom of information campaigners as a diluted form of what had been proposed in the White Paper. The full provisions of the act came into force on 1 January 2005. The Act was the responsibility of the Lord Chancellor's Department (now renamed the Ministry of Justice). However, freedom of information policy is now the responsibility of the Cabinet Office. The Act led to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Global Warming
Present-day climate change includes both global warming—the ongoing increase in global average temperature—and its wider effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global temperatures is driven by human activities, especially fossil fuel burning since the Industrial Revolution. Fossil fuel use, deforestation, and some agricultural and industrial practices release greenhouse gases. These gases absorb some of the heat that the Earth radiates after it warms from sunlight, warming the lower atmosphere. Carbon dioxide, the primary gas driving global warming, has increased in concentration by about 50% since the pre-industrial era to levels not seen for millions of years. Climate change has an increasingly large impact on the environment. Deserts are expanding, while heat waves and wildfires are becoming more common. Amplified warming in the Arctic has c ...

Weather Station
A weather station is a facility, either on land or sea, with instruments and equipment for measuring atmosphere of Earth, atmospheric conditions to provide information for weather forecasting, weather forecasts and to study the weather and climate. The measurements taken include temperature, atmospheric pressure, humidity, wind speed, wind direction, and precipitation amounts. Wind measurements are taken with as few other obstructions as possible, while temperature and humidity measurements are kept free from direct solar radiation, or insolation. Manual observations are taken at least once daily, while automated measurements are taken at least once an hour. Weather conditions out at sea are taken by ships and buoys, which measure slightly different meteorological quantities such as sea surface temperature (SST), wave height, and wave period. Drifting weather buoys outnumber their moored versions by a significant amount. Weather instruments A weather instrument is any device t ...
