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. This data is available to the public for a wide variety of uses including scientific research and analysis. completed historicalArchive NOAA National Centers for Environmental Information ncei.info@noaa.gov https://www.ncei.noaa.gov/contact NCEI Contact Information Information for contacts at NCEI. information pointOfContact NOAA National Centers for Environmental Information NCEI Geomagnetic Modeling Team geomag.models@noaa.gov pointOfContact asNeeded Associated HDGM2022 software may be updated as improvements are created. https://www.ngdc.noaa.gov/geomag/HDGM/images/hdgm_brazil.jpg Declination contour maps that compare HDGM to global magnetic field models JPG Earth Science > Solid Earth > Geomagnetism > Magnetic Field Earth Science > Solid Earth > Geomagnetism > Magnetic Intensity Earth Science > Solid Earth > Geomagnetism > Magnetic Declination Earth Science > Solid Earth > Geomagnetism > Magnetic Inclination theme Global Change Master Directory (GCMD) Science Keywords 2020-01-09 publication 9.1 NASA Goddard Space Flight Center, Earth Science Data and Information System https://earthdata.nasa.gov/about/gcmd/global-change-master-directory-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.
