Study of diurnal and seasonal variation of atmospheric trace gases is essential to understand our atmosphere. For this, daily zenith-sky scattered light observations have been made by UV-visible spectrometer during the period 200... see more

The migrating diurnal tide (DW1) presents a unique latitudinal structure in the stratosphere, mesosphere, and lower thermosphere. In this paper, the physical mechanisms that govern its seasonal variation are examined in these three regions using the 31.5-... see more

A great importance in developing the photosynthesis with the trees, bushes and herbal fruit plants is represented by the presence or absence of the inflorescences on the branches, the number of leaves, the foliar surface, the number of fruit. In this arti... see more

The equivalent slab-thickness  is very important in the study of the complex dynamics of the ionosphere as a result of its ability to determine the skewness of the ionospheric electron density profile. This study involves the day to day and monthly v... see more

Measurements of the magnetic component of the Schumann resonance in the frequency range 6-14 Hz were performedat high latitude location (TNB Antarctica; geographic coordinates: 74.7°S, 164.1°E; geomagnetic coordinates:80.0°S, 307.7°E; LT=UT+13; MLT=UT8; a... see more

Air pollution is an important public health issue. High levels of carbon monoxide in the atmosphere are hazardous to human health. Studies regarding the concentration of this and other gases in the atmosphere allow political actions to manage and reduce t... see more

PM2.5 data from major cities in the southern North China Plain during 2013–2015 were comprehensively analyzed relative to variation features, meteorology effects, and regional transport contributions. The annual average ranged from 87 to 123 μg m... see more

Most studies explored green-roof thermal effects on a few hot summer days based on short-term monitoring data. Few studies investigated the seasonal and diurnal patterns of thermal performance and associated weather effects. This research aims to address ... see more

Hourly sea levels recorded for the period (1992-1994) from a tide gauge at Gizan have been analyzed for low frequency oscillations. The major tidal constituents were identified and tides are described as semi-diurnal. Monthly mean sea level variations sho... see more
