Atmospheric transmission coefficient modelling in the infrared for thermovision measurements
نویسنده
چکیده
The aim of this paper is to discuss different models that describe atmospheric transmission in the infrared. They were compared in order to choose the most appropriate one for certain atmospheric conditions. Universal models and different inaccuracies connected with them were analysed in this paper. It is well known that all these models are different, but the aim of this paper is calculate how big the differences are between the characteristics of atmospheric transmission as a function of the distance. There have been models analysed from the literature, and these are used in infrared cameras. Correctly measured atmospheric transmission allows the correct temperature of an object to be determined, which is very vast problem that is discussed in paper.

Analysis of temporal and spatial correlation between precipitable water vapor retrievals from AIRS satellite sensor and 29 synoptic station measurements in Iran
Precipitable Water Vapor (PWV) is one of the most important quantities in meteorology and climate studies. PWV in Earth's atmosphere can be measured by Sun-photometer, the Atmospheric Infrared Sounder (AIRS), and radiosonde from surface, atmosphere and space-based systems, respectively. In this paper, we use PWV measured by Sun-photometer located in Institute for Advanced Studies in Basic Scien...
متن کاملConditions for the use of infrared camera diagnostics in energy auditing of the objects exposed to open air space at isothermal sky
Convective and radiation heat transfer take place between various objects placed in open air space and their surroundings. These phenomena bring about heat losses from pipelines, building walls, roofs and other objects. One of the main tasks in energy auditing is the reduction of excessive heat losses. In the case of a low sky temperature, the radiation heat exchange is very intensive and the t...

متن کاملMultiangle lidar performance in the presence of horizontal inhomogeneities in atmospheric extinction and scattering.
The performance of single-ended multiangle lidar for measurements of atmospheric extinction andbackscattering is analyzed in the presence of shot noise. An algorithm for determining the transmission coefficient in the presence of horizontal inhomogeneities is described. The analysis indicates that real-time measurements of atmospheric properties with the multiangle lidar may be feasible even in...
