DATSAV3 Surface Observations, 1901-continuing d463002 2003-06-16 publication National Climatic Data Center, NESDIS, NOAA, U.S. Department of Commerce author Air Force Combat Climatology Center, U.S. Air Force, U.S. Department of Defense author 557th Weather Wing, U.S. Air Force, U. S. Department of Defense author NSF National Center for Atmospheric Research publisher This ASCII data set (DATSAV3) is produced at the National Climatic Data Center (NCDC) from a USAF binary set (DATSAV2), a collection of worldwide surface weather observations from sources such as the the Global Telecommunications System (GTS) and Automated Weather Network (AWN). The Air Force Weather Agency (AFWA) decoded most of the collected observations for the Air Force Combat Climatology Center (AFCCC) where final decoding, validation, and quality control created DATSAV2. Mandatory data includes pressure, temperature, visibility, sky condition, and wind observation, but there may also be additional data, data remarks, or data element quality sections. NCDC provides quarterly updates to DSS, usually with a two-month delay. The earliest data is for 1901. The earliest years have the least volume of data, a few hundred megabytes; the volume in the 1950s-early 1960s increased by a factor of 10-20; 1965-1972 shows a decrease because of a loss of data; beginning in 1973 with about 5 gigabytes of data, volume has gradually increased to about 20 gigabytes per year. There are now about 10,000 active stations. Similar data sets prepared by the National Centers for Environmental Prediction (NCEP) are ds464.0 [http://rda.ucar.edu/datasets/ds464.0/] (beginning February 1975), and ds461.0 [http://rda.ucar.edu/datasets/ds461.0/] (beginning April 2000). This dataset has been superseded by ds463.3 [/datasets/ds463.3/]. onGoing datahelp@ucar.edu pointOfContact annually dataset Binary dataset Resource Type 2021-03-30 revision 4.4 DataCite Metadata Working Group orginator resourceTypeGeneral WEATHER STATIONS > WEATHER STATIONS FIXED OBSERVATION STATIONS > FIXED OBSERVATION STATIONS GROUND STATIONS > GROUND STATIONS METEOROLOGICAL STATIONS > METEOROLOGICAL STATIONS U.S. National Aeronautics and Space Administration Global Change Master Directory GCMD 2026-02-27 revision 23.4 NASA Global Change Master Directory orginator Valids List: Platforms AWDN > Automated Weather Data Network GTS > Global Telecommunications System U.S. National Aeronautics and Space Administration Global Change Master Directory GCMD 2026-02-27 revision 23.4 NASA Global Change Master Directory orginator Valids List: Projects EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC PRESSURE > SEA LEVEL PRESSURE EARTH SCIENCE > OCEANS > OCEAN WAVES > WAVE HEIGHT EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC WINDS > SURFACE WINDS EARTH SCIENCE > ATMOSPHERE > CLOUDS > CLOUD PROPERTIES > CLOUD BASE HEIGHT EARTH SCIENCE > ATMOSPHERE > ALTITUDE > STATION HEIGHT EARTH SCIENCE > ATMOSPHERE > CLOUDS > CLOUD TYPES EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC TEMPERATURE > SURFACE TEMPERATURE > MAXIMUM/MINIMUM TEMPERATURE EARTH SCIENCE > ATMOSPHERE > PRECIPITATION > SOLID PRECIPITATION > HAIL EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC WATER VAPOR > WATER VAPOR INDICATORS > DEW POINT TEMPERATURE EARTH SCIENCE > ATMOSPHERE > AIR QUALITY > VISIBILITY EARTH SCIENCE > OCEANS > OCEAN WAVES > WAVE PERIOD EARTH SCIENCE > ATMOSPHERE > CLOUDS > CLOUD PROPERTIES > CLOUD FREQUENCY EARTH SCIENCE > ATMOSPHERE > PRECIPITATION > SOLID PRECIPITATION > SNOW EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC PRESSURE > SURFACE PRESSURE EARTH SCIENCE > OCEANS > OCEAN TEMPERATURE > SEA SURFACE TEMPERATURE EARTH SCIENCE > ATMOSPHERE > PRECIPITATION > PRECIPITATION AMOUNT EARTH SCIENCE > ATMOSPHERE > ALTITUDE > GEOPOTENTIAL HEIGHT EARTH SCIENCE > OCEANS > OCEAN WAVES > WAVE SPEED/DIRECTION EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC TEMPERATURE > SURFACE TEMPERATURE > AIR TEMPERATURE EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC PRESSURE > PRESSURE TENDENCY U.S. National Aeronautics and Space Administration Global Change Master Directory GCMD 2026-02-27 revision 23.4 NASA Global Change Master Directory orginator Valids List: Science and Services Keywords Creative Commons Attribution 4.0 International License None eng utf-8 climatologyMeteorologyAtmosphere 1901-01 2008-05 NSF NCAR Geoscience Data Exchange datahelp@ucar.edu https://gdex.ucar.edu distributor 335209.628 https://gdex.ucar.edu/datasets/d463002/ https Dataset Description Related Link information https://gdex.ucar.edu/datasets/d463002/dataaccess/ https Data Access Related Link download none asNeeded
