background: measurement of background radiation is very important from different points of view especially for human health. the aim of this survey was focused on determining the current background radiation in one of the highest altitude regions ( zagros mountains ), chaharmahal and bakhtiari province, in the south west of iran . materials and methods: the outdoors-environmental monitoring exp...

Weather balloons are high-altitude meteorological particularly used for carrying scientific payloads into the upper atmosphere. These data obtained by using an instrument called as radiosonde which is attached to helium filled weather balloon measure it ascends up For more than 100 years, have given valuable information climate and research. In this paper, module designed with negligible risk o...

Kala-azar, a fatal infectious disease in many Indian states, particularly in Bihar, West Bengal, Uttar Pradesh, and Jharkhand, is caused by the protozoan parasite Leishmania donovani and transmitted by the sandfly vector Phlebotomus argentipes. The vector is distributed all over the country but the disease is confined to particular zones since before the last century. In this study, parameters ...

The theory of summation of electromagnetic line transitions is used to tabulate the Taylor expansion of the refractive index of humid air over the basic independent parameters (temperature, pressure, humidity, wavelength) in five separate infrared regions from the H to the Q band at a fixed percentage of Carbon Dioxide. These are least-squares fits to raw, highly resolved spectra for a set of t...

Water vapour, one of the dominant greenhouse gases, is a highly variable constituent of the Earth's atmosphere with a high latent heat. These two factors give it a key role in the development of atmospheric dynamics. Knowledge of the behaviour and distribution of water vapour in the atmosphere is crucial for understanding and predicting weather and climate. Unfortunately, atmospheric water vapo...

Vegetation indicators and spatial distribution characteristics are the core and basis to study the complex human-natural coupled system. In this paper, with Landsat 5 and Landsat 8 remote sensing data, we quantitatively estimated vegetation coverage in Henan Province, China. According to the urbanization rate, altitude, slope degree, and slope exposure, we analyzed spatial and temporal variatio...
