It updates the previous IGRF generation with a definitive main field model for epoch 2005.0, a main field model for epoch 2010.0, and a linear predictive secular variation meodel for 2010.0-2015.0. 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 Manoj Nair NOAA National Centers for Environmental Information 303-497-4642 Manoj.C.Nair@noaa.gov pointOfContact asNeeded This model is updated by IAGA every 5 years https://www.ngdc.noaa.gov/IAGA/vmod/img/vmod_header.gif IAGA Division V-MOD Header GIF 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 Earth Science > Solid Earth > Geomagnetism > Reference Fields theme Global Change Master Directory (GCMD) Science Keywords 2024 revision 19 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2024.

NCEI launched publicly on April 22, 2015. 2015-04-22T00:00:00 dataset Seven teams from the IAGA V-MOD group created independent candidate models for the IGRF-11. The models used the same datasets from satellites and land observatories with different criteria, filters, and processing steps. The various candidate models and their descriptions can be found at https://www.ngdc.noaa.gov/IAGA/vmod/candidatemodels.html NOAA National Centers for Environmental Information Geomagnetic Modeling Team geomag.models@noaa.gov http://www.ngdc.noaa.gov/geomag/ processor Processing steps were carried out individually by the developers of the model. Model Descriptions 2009-10-01 publication https://www.ngdc.noaa.gov/IAGA/vmod/candidatemodels.html processor Individual reports on algorithm and other criteria used should be referenced from the candidate model web page. The seven models were tested, evaluated, and compared by C.C. Finlay et al. The final model was calculated using weighted means of the candidates. The weights were agreed by a vote of the IGRF-11 task force. NOAA National Centers for Environmental Information Geomagnetic Modeling Team geomag.models@noaa.gov http://www.ngdc.noaa.gov/geomag/ processor Processing steps were carried out collectively by the developers of the model. The description of the evaluation and weighting process can be found in C.C. Finlay et al "Evaluation of IGRF-11 Candidate Models" in the Journal of Earth, Planets and Space.
