Solar radiation data are required for many applications and areas of research. In order to achieve this, several empirical models have been suggested predict the global solar in Turkey other countries. The different meteorological as radiation, sunshine duration, temperature, atmospheric pressure, wind speed relative humidity were measured by Eskisehir Osmangazi University during period between...

An on-going investigation using a tissue-equivalent proportional counter (TEPC) has been carried out to measure the ambient dose equivalent rate of the cosmic radiation exposure of aircrew during a solar cycle. A semi-empirical model has been derived from these data to allow for the interpolation of the dose rate for any global position. The model has been extended to an altitude of up to 32 km...

This paper reports on the performance of photovoltaic systems in the coastal zone of Antofagasta, northern Chile. This region is one of the most suitable places in the world for the use of solar energy due to the high solar radiation levels. However, this location is influenced by a coastal desert climate where the environmental effects on solar technologies are not well known. Therefore, we st...

The reliable quantification of ultraviolet (UV) radiation at the earth’s surface requires accurate measurements of spectral global solar UV irradiance in order to determine the UV exposure to human skin and to understand long-term trends in this parameter. Array spectroradiometers (ASRMs) are small, light, robust and cost-effective instruments, and are increasingly used for spectral irradiance ...

The annual mean maximum meridional heat transport (MHTMAX) differs by approximately 20% among coupled climate models. The value of MHTMAX can be expressed as the difference between the equator-topole contrast in absorbed solar radiation (ASR*) and outgoing longwave radiation (OLR*). As an example, in the Northern Hemisphere observations, the extratropics (defined as the region with a net radiat...

Nowadays, with the development of the economy, the demand for energy is increasing rapidly while the energy supply is growing shorter and shorter. Researches indicate that energy consumption in the residential sector counts for the main parts of the total energy consumption. This paper evaluates the effect of building orientation on exposure to the solar radiation in a NESW orientated case o...

The sun is the primary driver of terrestrial atmospheric phenomena and energy source for the earth. It emits radiation over a large energy band and ejects highly energetic plasma fluxes of charged particles into space. The sun is an active star that (i) goes through a 12-year maximum-minimum emission cycle, (ii) has huge, non-periodic eruptions in solar flares and coronal mass ejections, and (i...

mineral dust is produced from both natural and anthropogenic sources. dust aerosols can be transported over long distances in the atmosphere. they reduce the incident shortwave radiation to the surface by absorbing and scattering the solar radiation; thereby leading to a cooling effect at the surface and lower tropospheric temperature. on the other hand, by absorption and re-emission of longwav...
