gov.noaa.ncdc:C00023 National Climatic Data Center, NESDIS, NOAA, U.S. Department of Commerce Unknown tabular digital data http://www.ncdc.noaa.gov Tropical Storm Tracks for the North Atlantic, East, North, and Western Pacific (DSI-9697) is a historical digital data set archived at the National Climatic Data Center (NCDC). This file contains dates, tracks, wind speeds, and central pressure values (if available) for all tropical cyclones occurring over the 110-year period, 1886 through 1996. The tracks represented in the file are the 'best tracks'. Best tracks are constructed by the National Weather Service and the National Hurricane Center during post-analysis and all available information, including aircraft reconnaissance fixes, satellite imagery, land based radar fixes, ship reports, station reports and ocean buoy reports, are considered. Some discrepancies are found by the analyst, therefore, subjective interpretations are made and then smoothed to draw the 'best tracks'. The tracks are then digitized into three record images for each storm; Classification, Storm Data, and Title. To make a wide range of climatic data available to researchers and the public. data set C00023 RADAR ANEMOMETERS WIND VANES BAROMETERS THERMOMETERS VISUAL OBSERVATIONS DROPSONDES IMAGING RADIOMETERS WEATHER STATIONS AIRCRAFT SHIPS BUOYS SATELLITES National Climatic Data Center, NESDIS, NOAA, U.S. Department of Commerce 18860101 19961231 Ground Condition Complete As Needed 105.0 -10.0 75.0 0.0 ISO 19115 Topic Category climatologyMeteorologyAtmosphere 004 elevation 006 environment 007 oceans 014 DIF Discipline Keyword Thesaurus Earth Sciences > Atmosphere > Meteorology Earth Sciences > Atmosphere > Climatology Earth Sciences > Atmosphere > Weather Earth Sciences > Ocean > Oceanography GCMD Sciences Keyword Valids EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC PHENOMENA > CYCLONES EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC PHENOMENA > HURRICANES EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC PHENOMENA > TYPHOONS EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC PRESSURE > ANTICYCLONES/CYCLONES EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC PRESSURE > SEA LEVEL PRESSURE EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC PRESSURE > SURFACE PRESSURE EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC WINDS > SURFACE WINDS EARTH SCIENCE > OCEANS > OCEAN PRESSURE > SEA LEVEL PRESSURE EARTH SCIENCE > OCEANS > OCEAN WINDS > SURFACE WINDS GCMD Location Valids NORTH ATLANTIC OCEAN NORTH PACIFIC OCEAN GCMD Location Valids TROPOSPHERE SEA SURFACE WEATHER STATIONS RADAR WEATHER STATIONS VISUAL OBSERVATIONS WEATHER STATIONS WIND VANES WEATHER STATIONS ANEMOMETERS SHIPS ANEMOMETERS SHIPS WIND VANES SHIPS BAROMETERS SHIPS VISUAL OBSERVATIONS BUOYS BAROMETERS BUOYS WIND VANES BUOYS ANEMOMETERS AIRCRAFT VISUAL OBSERVATIONS AIRCRAFT BAROMETERS AIRCRAFT WIND VANES AIRCRAFT ANEMOMETERS AIRCRAFT DROPSONDES SATELLITES IMAGING RADIOMETERS 1 None None Unknown Unknown Completeness information not available.
