Dataset for "Latitudinal distribution of thermospheric density: Interplay of thermal expansion and circulation"

This dataset contains DE2 temperature and CHAMP mass density observation data normalized to an altitude of 400 km, as well as TIEGCM model simulation data for comparison with the observations. This dataset can be read through Matlab, and the plotting program is also included in the folder. The dataset is mainly used to investigate the mechanisms of the latitudinal variation of the thermospheric total mass density.
