The North–South Asymmetry of Martian Ionosphere and Thermosphere
Journal of Geophysical Research: Planets, 2021Based on Mars Atmospheric and Volatile EvolutioN's neutral composition and Langmuir probe electron density and temperature data, we statistically analyzed the climatic variations of the Martian thermosphere and ionosphere and found significant north ...

We analyzed the daily sunspot-group data reported by the Greenwich Photoheliographic Results (GPR) during the period 1874 – 1976 and Debrecen Photoheliographic Data (DPD) during the period 1977 – 2017 and studied North–South asymmetry in the maxima and ...

Forecasting the amplitude and timing of the sunspot cycle is highly important for solar physics and space weather applications, but high-precision prediction of solar magnetic activity has remained an outstanding challenge.

Implications of Titan's north–south brightness asymmetry
Nature, 1981Voyager 1 images of Titan, when normalized to remove limb darkening, reveal an axially symmetric brightness pattern with significant north-south asymmetry. This interhemispheric contrast seems to be a response to seasonal solar heating variations resulting from Titan's inclined spin axis.

A North–South asymmetry in thermospheric density
Advances in Space Research, 2006Abstract Utilizing the opportunity that our previously analyzed drag material covers the whole latitude interval between 84°N and 84°S, we have reanalyzed our 16 thousand observed total density data comparing them with model densities as a function of different parameters.

In this work, we apply multichannel singular spectrum analysis (MSSA), a data-adaptive, multivariate, non-parametric technique that simultaneously exploits the spatial and temporal correlations of the input data to extract common modes of variability, to

North-south asymmetry in mesospheric ozone
Planetary and Space Science, 1986Abstract Available rocket ozone data at Woomera (31°S, 136°E) and Kagoshima (31°N, 131°E) were analysed to construct mean profiles. A comparison of the two profiles indicates the higher ozone concentrations at Woomera originating mainly in the summer season.

Abstract For seven selected magnetically quiet days in 1955 and 1958 synoptic analyses of S q by 3-hr intervals have been made. The representative current patterns show a persistent NS asymmetry, in the sense that the southern vortex lags behind the northern vortex, sometimes as much as 60°.
