System of Imaging Photometers for Upper Atmospheric Phenomena Study in the Arctic Region

Atmosphere, 2022
A Pulsating Aurora Imaging Photometers Stereoscopic System (PAIPS) is suggested and described in the paper. The system is based on two lens telescopes with a matrix of multianode photomultiplier tubes as photodetectors placed in two high latitude ...

Quantifying Polar Mesospheric Clouds Thermal Impact on Mesopause

Atmosphere
The article is focused on the quantitative assessment of the thermal impact of polar mesospheric clouds (PMCs) on the mesopause caused by the emission of absorbed solar and terrestrial infrared (IR) radiation by cloud particles.

What to Do When the F10.7 Goes Out?

Space Weather, 2023
The solar radio flux at 10.7 cm, known as F10.7, is a critical operational space weather index. However, without a clear backup, any interruption to the service can result in substantial errors in model outputs.

Evaluation of SMOS Sea Surface Salinity with Argo data along the Exclusive Economic Zone (EEZ) of Pakistan

Egyptian Journal of Remote Sensing and Space Sciences
Ocean-Atmosphere interactions have been gradually recognized to play a significant role in hydrological cycle and climate change. It is essential to understand ocean-circulation behaviour, including the Sea Surface Salinity (SSS) which is a root cause of

MANIFESTATION OF SOLAR ACTIVITY AND DYNAMICS OF THE ATMOSPHERE IN VARIATIONS OF 577.7 AND 630.0 nm ATMOSPHERIC EMISSIONS IN SOLAR CYCLE 24

Solar-Terrestrial Physics, 2020
In the paper, variations of the night emission intensities in the 557.7 and 630 nm atomic oxygen lines [OI] in 2011–2019 have been analyzed. The analysis is based on data from the ISTP SB RAS Geophysical Observatory. The emission intensities are compared

Seasonal Cycle of the Total Ozone Content over Southern High Latitudes in the CCM SOCOLv3

Atmosphere
The severe ozone depletion over the Southern polar region, known as the “ozone hole,” is a stark example of global ozone depletion caused by human-made chemicals. This has implications for climate change and increased harmful surface solar UV.

Registering upper atmosphere parameters in East Siberia with Fabry–Perot Interferometer KEO Scientific “Arinae”

Solar-Terrestrial Physics, 2017
We describe the Fabry—Perot interfero-meter designed to study Earth’s upper atmosphere. We propose a modification of the existing data processing method for determining the Doppler shift and Doppler widening and also for separating the observed line ...
