Measurements during daytime and during periods of strong solar activity are contaminated
by external current systems, which are difficult to accurately model. Therefore,
only nighttime data during magnetically quiet periods were used in generating the
WMM coefficients.

Some contributions to the measured magnetic field, such as the diamagnetic effect
of ionospheric plasma (Lühr et al, 2003) or motional induction by tidal ocean currents
(Kuvshinov and Olsen, 2005; Maus, 2007), can be accurately modeled and were corrected
for prior to the generation of the WMM main field coefficients.

To account for the contributions that have not been removed in the previous steps,
an extended set of model parameters is co-estimated with the WMM model coefficients.
These account for smaller-wavelength internal magnetic field contributions (spherical
harmonic degree larger than 12), second time derivatives (secular acceleration) and
contributions from currents external to the Earth. The set of WMM coefficients plus
the extended model parameters is called a parent model of the WMM. Two different
parent models were produced, reflecting different modeling strategies employed by
NGDC for the main field model and BGS for the secular variation model.

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.
