Description:

Abstract:

These data are vector and scalar component values of the Earth's magnetic field for the Boulder Magnetic Observatory in Colorado. 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.

Purpose:

To provide ground-based, calibrated values of the Earth's magnetic field at a specific location for scientific research and practical applications.

Attribute_Accuracy:

Attribute_Accuracy_Report:

Data from the Boulder Magnetic Observatory met the requirements for being an INTERMAGNET Magnetic Observatory (IMO), and as such met the specifications listed in theINTERMAGNET Technical Manual (http://www.intermagnet.org//im_manual.pdf)

Logical_Consistency_Report:

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.

Completeness_Report:

These data represent the complete record set for this station and this year.
