Simulations of the ionospheric annual asymmetry: Sun-Earth distance effect
It has been suggested that the difference of the Sun-Earth distance between the December and June solstices has a great impact on the ionospheric annual asymmetry. In this...- publication PDF

High-cadence visible and infrared spectra of the Sun during eclipse
We study novel spectra from 310 nm to 5.5 mu m obtained during the 2017 August 21 eclipse. Four spectrometers were deployed at Camp Wyoba (altitude 2402 m) on Casper Mountain,...- publication PDF

Hydrodynamic planetary thermosphere model: 1. Response of the Earth's...
It has been suggested that the exobase temperature of early terrestrial planetary atmosphere could have reached over 10,000 K. Although such high exobase temperatures should...- publication PDF

An air stagnation index to qualify extreme haze events in northern China
Stagnation weather affects atmospheric diffusion ability, and hence causes the occurrence of haze events, which have been happening frequently in northern China (NC). This work...- publication PDF
