gov.noaa.ncdc:C00084 National Climatic Data Center, NESDIS, NOAA, U.S. Department of Commerce Unknown tabular digital data http://www.ncdc.noaa.gov Hourly Solar Radiation Data is historical data set DSI-9725 archived at the National Climatic Data Center (NCDC). Elements included are total solar radiation measured in Langleys per hour, solar elevation, extraterrestrial radiation and various surface observations ranging from temperature and dew point to type of precipitation, snow cover and cloud layer parameters. This data set covers approximately 50 stations in the United States and in the Pacific area. A few stations have records beginning in December 1951. The remaining stations began observations in July 1952. Hourly surface observations were recorded in Local Standard Time. Prior to June 1, 1957, the surface observations were taken 20-30 minutes past the hour. From June 1, 1957 through December 31, 1964, the surface observations were taken a few minutes before the hour. From July 1, 1958 to the end of this observation period the solar data are for the hour ending on the hour punched. This change made the hourly data compatible with the times of the surface observation on Form WBAN 10. To make a wide range of climatic data available to researchers and the public. data set C00084 CEILOMETERS PSYCHROMETERS PYRANOMETERS THERMOMETERS VISUAL OBSERVATIONS WEATHER STATIONS National Climatic Data Center, NESDIS, NOAA, U.S. Department of Commerce 19520101 19761231 Ground Condition Complete As Needed 130.0 -60.0 72.0 -15.0 ISO 19115 Topic Category climatologyMeteorologyAtmosphere 004 elevation 006 DIF Discipline Keyword Thesaurus Earth Sciences > Atmosphere > Meteorology Earth Sciences > Atmosphere > Climatology Earth Sciences > Atmosphere > Weather Earth Sciences > Land > Hydrology GCMD Sciences Keyword Valids EARTH SCIENCE > ATMOSPHERE > AIR QUALITY > VISIBILITY EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC PHENOMENA > FOG EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC RADIATION > INCOMING SOLAR RADIATION EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC RADIATION > SUNSHINE EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC RADIATION > NET RADIATION EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC WATER VAPOR > DEW POINT EARTH SCIENCE > ATMOSPHERE > CLOUDS > CLOUD AMOUNT/FREQUENCY EARTH SCIENCE > ATMOSPHERE > CLOUDS > CLOUD BASE EARTH SCIENCE > ATMOSPHERE > CLOUDS > CLOUD CEILING EARTH SCIENCE > ATMOSPHERE > CLOUDS > CLOUD HEIGHT EARTH SCIENCE > ATMOSPHERE > CLOUDS > CLOUD TYPES EARTH SCIENCE > ATMOSPHERE > CLOUDS > CLOUD VERTICAL DISTRIBUTION EARTH SCIENCE > ATMOSPHERE > PRECIPITATION > FREEZING RAIN EARTH SCIENCE > ATMOSPHERE > PRECIPITATION > HAIL EARTH SCIENCE > ATMOSPHERE > PRECIPITATION > PRECIPITATION RATE EARTH SCIENCE > ATMOSPHERE > PRECIPITATION > RAIN EARTH SCIENCE > ATMOSPHERE > PRECIPITATION > SLEET EARTH SCIENCE > ATMOSPHERE > PRECIPITATION > SNOW EARTH SCIENCE > CRYOSPHERE > SNOW/ICE > SNOW COVER EARTH SCIENCE > HYDROSPHERE > SNOW/ICE > SNOW COVER EARTH SCIENCE > SPECTRAL/ENGINEERING > VISIBLE WAVELENGTHS > VISIBLE RADIANCE GCMD Location Valids UNITED STATES OF AMERICA GUAM AMERICAN SAMOA MARSHALL ISLANDS MICRONESIA PALAU GCMD Location Valids TROPOSPHERE STRATOSPHERE LAND SURFACE WEATHER STATIONS PYRANOMETERS WEATHER STATIONS CEILOMETERS WEATHER STATIONS VISUAL OBSERVATIONS WEATHER STATIONS PSYCHROMETERS WEATHER STATIONS THERMOMETERS 1 None None Unknown Unknown Unknown Unknown Unknown COLUMN: 1-5 ELEMENT: Station Number CODE: 00001-99999 DEFINITION: WBAN Number COLUMN: 6-7 ELEMENT: Year CODE: 51-99 DEFINITION: Last two digits of year COLUMN: 8-9 ELEMENT: Month CODE: 01-12 DEFINITION: January-December COLUMN: 10-11 ELEMENT: Day CODE: 01-31 DEFINITION: Day of Month COLUMN: 12-13 ELEMENT: Hour LST CODE: 00-23 DEFINITION: Solar hour is one hour later than LST COLUMN: 14-17 ELEMENT: Radiation Langleys per hour CODE: 0000-9999 DEFINITION: 0.0 - 999.9 Langleys to tenths COLUMN: 18-19 ELEMENT: Solar Elevation CODE: 01-90 DEFINITION: 1-90 whole degrees COLUMN: 20-22 ELEMENT: Extra-terrestrial radiation CODE: 001-999 DEFINITION: 1 - 999 whole Langleys per hour COLUMN: 23-24 ELEMENT: Sunshine CODE: 00-60 DEFINITION: 0 - 60 minutes COLUMN: 25 ELEMENT: Snow cover CODE: 0 or blank DEFINITION: None or trace of snow CODE: 1 DEFINITION: One inch or more COLUMN: 33 ELEMENT: Snow cover CODE: 0 or blank DEFINITION: None or trace of snow CODE: 1 DEFINITION: One inch or more Note: This column was used for snow cover from the beginning of the the program until 10/01/59, when it was changed to column 25.
