The initial version of Global Historical Climatology Network was developed in the summer of 1992. [3] This first version, known as Version 1 was a collaboration between research stations and data sets alike to the World Weather Records program and the World Monthly Surface Station Climatology from the National Center for Atmospheric Research.

The data is stored in GRIB format. The reanalysis was done in an effort to improve the accuracy of historical weather maps and aid in a more detailed analysis of various weather systems through a period that was severely lacking in computerized data.
The United States National Climatic Data Center (NCDC), previously known as the National Weather Records Center (NWRC), in Asheville, North Carolina, was the world's largest active archive of weather data. In 2015, the NCDC merged with two other federal environmental records agencies to become the National Centers for Environmental Information ...
GRIB (GRIdded Binary or General Regularly-distributed Information in Binary form [1]) is a concise data format commonly used in meteorology to store historical and forecast weather data. It is standardized by the World Meteorological Organization 's Commission for Basic Systems, known under number GRIB FM 92-IX, described in WMO Manual on Codes ...
UAH provide data on three broad levels of the atmosphere. The Lower troposphere - TLT (originally called T2LT). The mid troposphere - TMT; The lower stratosphere - TLS [3] Data are provided as temperature anomalies against the seasonal average over a past basis period, as well as in absolute temperature values. The baseline period for the ...
Old Weather is a Zooniverse project and is a collaboration between researchers at many institutions, including the University of Oxford, Oxford Martin School, ACRE (International Atmospheric Circulation Reconstructions over the Earth), Naval-History.Net of Penarth, Jisc which encourages UK colleges and universities in the innovative use of digital technologies, the National Maritime Museum at ...
In addition to viewing gridded weather data via the internet, users can download and use the individual grids using a "GRIB2 decoder" which can output data as shapefiles, netCDF, GrADS, float files, and comma-separated value files. [32] Specific points in the digital database can be accessed using an XML SOAP service.
Through the 1970s the unit worked on interpreting documentary historical records. From 1978 onward CRU began production of its gridded data set of land air temperature anomalies based on instrumental temperature records held by National Meteorological Organisations around the world. In 1986 sea temperatures were added to form a synthesis of ...
