Users should not use this version except in rare cases (e.g., when reproducing previous studies that used this version).** The Global Historical Climatology Network - Daily (GHCN-Daily) dataset addresses the need for historical daily records over global land areas. Like its monthly counterpart (GHCN-Monthly), GHCN-Daily is a composite of climate records from numerous sources that were merged and then subjected to a suite of quality assurance reviews. The meteorological elements measured for the data set include, but are not limited to, daily maximum and minimum temperature, temperature at the time of observation, precipitation (i.e., rainfall and snow water equivalent), snowfall and snow depth. GHCN-Daily serves as the official archive for daily data from the Global Climate Observing System (GCOS) Surface Network (GSN) and is particularly well suited for monitoring and assessment activities related to the frequency and magnitude of extremes. Sources for the GHCN-Daily data set include, but are not limited, to U.S. Cooperative Summary of the Day, U.S. Fort data, U.S. Climate Reference Network, Community Collaborative Rain, Hail and Snow Network, and numerous international sources. The dataset contains measurements from over 75,000 stations worldwide,about two thirds of which are for precipitation measurement only. Approximately 8500 are regularly updated with observations from within the last month. While most of these sites report precipitation, daily maximum and minimum temperatures are available at more than 25,000 of them, and over 24,000 contain records of snowfall and/or snow depth. The process of integrating data from multiple sources into the GHCN-Daily dataset takes place in three steps: screening the source data for stations whose identity is unknown or questionable; classifying each station in a source dataset either as one that is already represented in GHCN-Daily or as a new site; and mingling the data from the different sources. The first two of these steps are performed whenever a new source dataset or additional stations become available, while the actual mingling of data is part of the automated processing that creates GHCN-Daily on a regular basis. GHCN-Daily data are subject to a suite of quality assurance checks. The checks consist of several types of carefully evaluated tests that detect duplicated data, climatological outliers, and various inconsistencies (internal, temporal, and spatial). Manual review of random samples of flagged values was used to set the threshold for each procedure such that the tests false-positive rate is minimized. In addition, the tests are performed in a deliberate sequence in an effort to enhance the performance of the later checks by detecting errors with the checks applied earlier in the sequence. The GHCN-Daily was developed to meet the needs of climate analysis and monitoring studies that require data at a sub-monthly time resolution (e.g., assessments of the frequency of heavy rainfall, heat wave duration, etc.). It also serves as NCDC's sole source of U.S. Summary of the Day data, providing a diverse array of users in the public and private sector with weather and climate observations that meet needs from the local to national level. By bringing together contributions from dozens of national and international sources and combining historical with near real-time observations, this dataset helps users understand todays climate and how it impacts society while helping users prepare for weather and climate conditions in the future. superseded DOC/NOAA/NESDIS/NCEI > National Centers for Environmental Information, NESDIS, NOAA, U.S. Department of Commerce GHCN-Daily Operations Team +1 828-271-4800 +1 828-271-4876 151 Patton Avenue Veach-Baley Federal Building, Room 468 Asheville NC 28801-5001 USA ncdc.ghcnd@noaa.gov 8:00 - 6:00 Eastern pointOfContact notPlanned Earth Science > Atmosphere > Atmospheric Temperature > Surface Temperature > Maximum/Minimum Temperature Earth Science > Atmosphere > Atmospheric Temperature > Surface Temperature > Air Temperature Earth Science > Atmosphere > Precipitation > Precipitation Amount Earth Science > Atmosphere > Precipitation > Solid Precipitation > Snow Earth Science > Terrestrial Hydrosphere > Snow/Ice > Snow Depth theme Global Change Master Directory (GCMD) Science Keywords 2018 revision Version 8.6 Global Change Data Center, Science and Exploration Directorate, Goddard Space Flight Center (GSFC) National Aeronautics and Space Administration (NASA) https://earthdata.nasa.gov/about/gcmd/global-change-master-directory-gcmd-keywords HTTPS Web Browser Global Change Master Directory (GCMD) Keywords The information provided on this page seeks to define how the GCMD Keywords are structured, used and accessed.

In general, the stations providing daily observations were not managed to meet the desired standards for climate monitoring. Rather, the stations were deployed to meet the demands of agriculture, hydrology, weather forecasting, aviation, etc. GHCN-Daily data have not been homogenized to account for the potential artifacts associated with the various reporting practices at stations. Users must consider whether the potential for changes in systematic bias might be important for their particular application. otherRestrictions **Please note, this dataset has been superseded by a newer version.
