Surprisingly Large Carbon Uptake by North American Biosphere During El Niños
New analysis of NOAA’s long-term air samples by CIRES and NOAA scientists finds that the North American terrestrial biosphere takes up unexpectedly large amounts of carbon in response to elevated carbon dioxide levels during El Niño years.
Modeling Earth’s Geomagnetic Fields
Scientists use many instruments to measure Earth’s magnetic fields. Satellite, airborne, marine, and land-based observations show the position and strength of Earth’s invisible magnetism. NOAA scientists generate the model from a combination of satellite and ground-based data, as well as airborne and marine magnetic data compiled into the Earth Magnetic Anomaly Grid (EMAG2). From these, scientists create the HDGM to show fields of magnetism and their annual fluctuations. Known for its accuracy, the HDGM is the most advanced model to track changes in the global magnetic field.
