Gravity Data for the State of Nevada

Gravity data for the entire state of Nevada and adjacent parts of California, Utah, and Arizona are presented. About 80,000 gravity stations were compiled primarily by the U.S. Geological Survey. Gravity data were reduced to the Geodetic Reference System of 1967 and adjusted to the International Gravity Standardization Net 1971 gravity datum. Data were processed to complete Bouguer and isostatic gravity anomalies by applying standard gravity corrections including terrain corrections and isostatic corrections. This data set was received in October, 1997 as a published USGS CD-ROM. For further information, see "Gravity Data of Nevada, by David A. Ponce, U.S. Geological Survey Digital Data Series DDS-42, 1997". A documentation file(readme.txt), describes the contents of this collection and includes a description of the data reduction process, selected principal fact references, and a list of sources for the data.

Alaska East-West Deflections (DEFLEC96)

This 2' x 4' surface deflection of the vertical grid for Alaska is the DEFLEC96 model. The computation used about 1.1 millionterrestrial and marine gravity data held in the National Geodetic Survey gravity data base in July 1996. These data were augmented by gravitydata contributions from NGA (former National Imagery and Mapping Agency (former Defence Mapping Agency)). The deflections were obtained by numerical differentiation of cubic spline models along the parallels of the GEOID96 grid. The gravity values are based on the International Gravity Standardization Net 1971 (IGSN71).The deflections are referred to the Geodetic Reference System 1980 (GRS80) ellipsoidal normals. The curvature of the plumb line correction has been applied. We are particularly grateful to NGA (former National Imagery and Mapping Agency) for their assistance and their data contributions.

Magnetic Field Calculator

The Magnetic Field Calculator will calculate the total magnetic field, including components (declination, inclination, horizontal intensity, northerly intensity, easterly intensity, vertical intensity) and the annual change for each. Each calculation is for a specific location, elevation and date or range of dates.  The calculated result can be obtained from two separate geomagnetic models, the IGRF11 or the WMM2010. Declination is calculated using the current World Magnetic Model (WMM) or International Geomagnetic Reference Field (IGRF) model. While results are typically accurate to 30 minutes of arc, users should be aware that several environmental factors can cause disturbances in the magnetic field.

High Definition Geomagnetic Model 2021 Real-Time Disturbance Calculator

The High Definition Geomagnetic Model (HDGM) is a global, high resolution model of the Earth's geomagnetic main and crustal field, providing magnetic field values (total field, dip, and declination) at any point above or below the Earth's surface. Well planners can use HDGM to compute magnetic reference values at any point, as well as easily integrate HDGM into their directional drilling software. HDGM is updated annually to correctly model secular changes in the geomagnetic field. The US National Oceanic and Atmospheric Administration (NOAA), in partnership with the directional drilling industry and the University of Colorado have developed a real-time component for NOAA's High Definition Geomagnetic Model. HDGM-RT improves the HDGM by accurately modeling the magnetic fields originating in the Earth's magnetosphere in real-time using a combination of solar-wind observing satellites situated between Earth and sun and a chain of geomagnetic observatories on the Earth's surface. The model also includes an ionospheric field model calculated from a combination of observatory and Swarm satellite data in order to represent the daily variations in the ionosphere. The addition of HDGM RT can save rig-time and reduce the drilling cost by enabling improved drill string interference correction during adverse space weather conditions.

EMAG2v3: Earth Magnetic Anomaly Grid (2-arc-minute resolution)

EMAG2v3 is a global Earth Magnetic Anomaly Grid compiled from satellite, ship, and airborne magnetic measurements.  It is a significant update of the previous release of the Earth Magnetic Anomaly Grid. The resolution remains 2 arc-minutes, and the altitude of 4 km above the geoid is still supported, but an additional product, a grid that is observed at sea-level over oceanic regions, has been produced. New additions grid and track line data have been included, both over land and the oceans. Wherever available, the original shipborne and airborne data were used instead of precompiled oceanic magnetic grids. Interpolation between sparse track lines in the oceans was improved by using a kriging algorithm, which specializes in heterogeneous data distribution gridding, in order to create a compilation as true to the observed data as possible, and avoid using a priori information. The longest wavelengths (>300 km) were replaced with the latests satellite lithosphere magnetic field model, MF7.
