GHCN (Global Historical Climatology Network) - Daily, from the National Oceanic and Atmospheric Administration (NOAA), is an integrated database of daily climate summaries from land surface stations across the globe. The data are obtained from numerous sources and integrated and subjected to a common suite of quality assurance reviews. GHCN-Daily contains records from over 90,000 stations in 180 countries and territories. Numerous daily variables are provided, including maximum and minimum temperature, total daily precipitation, snowfall, and snow depth; however, about two-thirds of the stations report precipitation only. Both the record length and period of record vary by station and cover intervals ranging from less than one year to more than 175 years.
In Data-Planet, the GHCN is presented as two datasets:
The National Oceanic and Atmospheric Administration (NOAA), within the United States Department of Commerce, was formed by Reorganization Plan No. 4 of 1970. Its mission is to monitor and assess the state of the environment in order to make accurate and timely forecasts to protect life, property, and natural resources, as well as to promote the economic well-being of the US and to enhance its environmental security. The National Climatic Data Service within NOAA provides weather, water, and climate warnings, forecast, and data for the US and adjacent waters.
According to a paper by Matthew J. Menne, et al, "An Overview of the Global Historical Climatology Network Daily Database" (published online July 1, 2012, http://dx.doi.org/10.1175/JTECH-D-11-00103.1), the analysis of multi-decadal climate trends and variability are commonly based on monthly and annual time series of station-based climate observations. However, other climate studies require daily data. Menne et al provide several examples:
