Variations in Ozone Concentration over the Mid-Latitude Region Revealed by Ozonesonde Observations in Pohang, South Korea

Atmosphere, 2020
Ozone absorbs harmful UV rays at high elevations but acts as a pollutant gas in the lower atmosphere. It is necessary to monitor both the vertical profile and the total column ozone.

Disquisitions Relating to Principles of Thermodynamic Equilibrium in Climate Modelling

Entropy, 2022
We revisit the fundamental principles of thermodynamic equilibrium in relation to heat transfer processes within the Earth’s atmosphere. A knowledge of equilibrium states at ambient temperatures (T) and pressures (p) and deviations for these p-T states ...

The tropospheric scintillation prediction of earth-to-satellite link for Bangladeshi climatic condition [PDF]

Serbian Journal of Electrical Engineering, 2015
The performance of earth-to-satellite link largely depends on various environmental factors like rain, fog, cloud, and atmospheric effects like ionospheric and tropospheric scintillation.
