formerly the National Geophysical Data Center (NGDC)... more on NCEI
NOAA’s former three data centers have merged into the National Centers for Environmental Information (NCEI).
Help us improve the accuracy of magnetic navigation by tracking changes in Earth's magnetic field with the CrowdMag app.
NCEI has updated the Enhanced Magnetic Model to accurately represent the Earth’s magnetic field at a high resolution.
We add value to data through research, data modeling, and producing derived products.
Online calculators, Interactive Maps and Web Services facilitate access to data in the archive.
We provide stewardship, products, and services for geophysical data from our Sun to Earth and Earth's sea floor and solid earth environment, including Earth observations from space.
Active in many international programs, we offer scientists around the world access to global databases through international exchange.
