Vector values are measured using 3 mutually orthogonal fluxgate magnetometer sensors. The scalar value of the total magnetic field is recorded with a proton precession magnetometer. All values are calibrated with measurements of the absolute value of the geomagnetic field using a DI-Flux magnetometer. The data are numerically filtered to prevent aliasing, and quality controlled during processing. Longer period values of the field, including hourly, daily, monthly, and annual means are derived from the 1-minute data. To provide ground-based, calibrated values of the Earth's magnetic field at a specific location for scientific research and practical applications. completed asNeeded BOU04BLV.JPG Baseline values for the Boulder calibration data for 2004 JPEG Earth Science > Solid Earth > Geomagnetism Earth Science > Solid Earth > Geomagnetism > Geomagnetic Indices Earth Science > Solid Earth > Geomagnetism > Magnetic Declination Earth Science > Solid Earth > Geomagnetism > Magnetic Field Earth Science > Solid Earth > Geomagnetism > Magnetic Inclination Earth Science > Solid Earth > Geomagnetism > Magnetic Intensity theme NASA/GCMD Earth Science Keywords DOC/NOAA/NESDIS/NCEI > National Centers for Environmental Information, NESDIS, NOAA, U.S. Department of Commerce DOC/NOAA/NESDIS/NGDC > National Geophysical Data Center, NESDIS, NOAA, U.S. Department of Commerce dataCentre Global Change Master Directory (GCMD) Data Center Keywords 2020-01-09 publication 9.1 NASA Goddard Space Flight Center, Earth Science Data and Information System https://www.earthdata.nasa.gov/learn/find-data/idn/gcmd-keywords Global Change Master Directory (GCMD) Keywords The information provided on this page seeks to define how the GCMD Keywords are structured, used and accessed.

NCEI launched publicly on April 22, 2015. 2015-04-22T00:00:00 dataset These data represent the complete record set for this station and this year. Various methods are used to check the integrity of the data. These include: (1) making comparisons between the total intensity values computed from the vector magnetometer and those measured by the scalar magnetometer, (2) comparing the field values reduced using the calibration data with those obtained during the weekly absolute measurements, and (3) visually inspecting the data and comparing with other stations.
