The eleventh generation of the International Geomagnetic Reference Field (IGRF) was adopted in December 2009 by the International Association of Geomagnetism and Aeronomy Working Group V-MOD. 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.

NOAA National Centers for Environmental Information
NOAA created the National Centers for Environmental Information (NCEI) by merging NOAA's National Climatic Data Center (NCDC), National Geophysical Data Center (NGDC), and National Oceanographic Data Center (NODC), including the National Coastal Data Development Center (NCDDC), per the Consolidated and Further Continuing Appropriations Act, 2015, Public Law 113-235. NCEI launched publicly on April 22, 2015.

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

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.
