Modeling of regional magnetic field applying spherical functions: practical aspect

Геофизический журнал, 2019
Modeling of geomagnetic field and creation of geomagnetic maps is one of the main directions of geomagnetic studies. For constructing global model the global spherical Lejeandre functions are used in most cases, though for constructing regional magnetic ...

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.
