The global configuration of the geomagnetic field shows that the maximum east-west difference in geomagnetic declination of northern middle latitude lies in the US region (~32\textdegree), which produces the significant ionospheric east-west coast difference in terms of total electron content first revealed by Zhang et al. (2011). For verification, it is valuable to investigate this feature over the Far East area, which also shows significant geomagnetic declination east-west gradient but smaller (~15\textdegree) than tha ...

Study on near-far ultraviolet imaging spectrometer with high resolution A near-far ultraviolet imaging spectrometer with high resolution is developed，which can be applied to the upper atmosphere observation in 115nm-295nm. The application demands of the corresponding remote sensing are analyzed. Because the imaging spectrum technology has been rarely utilized for the ionosphere observation in our country, we study some foreign advanced loads to apply the standard to our design. According to the analysis, the optical system of the imaging spectrometer is designed. The system includes an off- ...

The Wind Imaging Interferometer (WINDII) was launched on the NASA\textquoterights Upper Atmosphere Research Satellite on 12 September 1991 and operated until 2003. Its role in the mission was to measure vector winds in the Earth\textquoterights atmosphere from 80 to 110 km, but its measurements extended to nearly 300 km. The approach employed was to measure Doppler shifts from a suite of visible region airglow lines emitted over this altitude range. These included atomic oxygen O(1S) and O(1D) lines, ...

Research on Retrieving Thermospheric O/N2 from FUV Remote Sensing Magnetic storms usually cause significant departures of thermospheric O and N2\ from their normal values. To study the effects on thermospheric neutral species caused by magnetic storms, a method to retrieve thermospheric O/N2\ based on the data obtained from global ultraviolet imager on board TIMED is presented. With the help of AURIC, the normalizations of observing angles and SZAs were preformed to the measurements and a relationship between 135.6/LBHs and O/N2\ was estab ...

The Ionospheric Mid-Latitude Summer Nighttime Anomaly This paper presents monthly variations of the mid-latitude summer nighttime anomaly (MSNA) of the ionosphere for the first time by using global observations of the FORMOSAT-3/COSMIC (F3/C), NASA TIMED-GUVI, ground-based radars and GPS receiver network. The MSNA is characterized by greater nighttime (19:00 LT - 24:00 LT, or period of larger solar zenith angles) ionospheric electron density than that during daytime (08:00 - 18:00 LT, or period of smaller solar zenith angles) at middle latitudes during solstices.
