Models and predictions of Earth’s magnetic field based on geomagnetic observatory data

Earth, Planets and Space
Observations of the geomagnetic field taken at Earth’s surface are processed to construct a set of continuous models of the geomagnetic field and its secular variation from 1956 to 2033.

Dependence of Simulations of Upper Atmospheric Microwave Sounding Channels on Magnetic Field Parameters and Zeeman Splitting Absorption Coefficients

Remote Sensing
The upper atmospheric microwave sounding channels data are important for atmospheric data assimilation and retrieval. However, radiative transfer simulation accuracy is constrained by the precise characterization of the Zeeman splitting effect.
