Semiautomatic Twilight Photometer, Design and Working
نویسندگان
چکیده
Aerosol measurements have been carried out at Kolhapur (16.41°N 74.13°E) by using newly designed Semiautomatic Twilight Photometer. Some noticeable features of the semiautomatic twilight photometer are improvement in efficiency of the system, growth in signal to noise ratio, augmentation in height resolution, lot of upgrading in the sensitivity of the system, expansion in duration of operation of the system, rise in rate of sampling, better accuracy in storing the data etc. The twilight scattering method yields a reasonable qualitative picture of the vertical distribution of the aerosols from about 6 km to a maximum of 350 km.

Fast Pre-amplifier Designed for Semiautomatic Twilight Photometer
Fast Pre-amplifier is designed for Semiautomatic twilight photometer, used for aerosol measurements over Kolhapur (16°42′N, 74°14′E). This amplifier is designed and developed by connecting 10 single IC amplifiers in parallel. The efficiency of the system is increased by adopting multiple pre-amplifier configuration which improves signal to noise ratio by factor of 10 and this fact is responsibl...
متن کاملDesign, construction and calibration of single channel sun-photometer for study of aerosols
Aerosols are tiny liquid or solid particles suspended in the air have a strong influence on air quality, human health and climate change. Sun-photometer is a tool for measuring the optical and physical characteristics of aerosols by using sunlight at various wavelengths from the Earth surface. In this paper, the design, construction, and calibration of a single channel sun-photometer is present...
متن کاملStudy of Aerosol Vertical Profiles during Cloudy Days
Aerosol measurements have been carried out at Kolhapur (16°42′N, 74°14′E) by using Twilight Photometer, which is indigenously designed and developed at the Indian Institute of Tropical Meteorology, a tropical station, Pune. The basic principle of this technique is if more number of aerosols exists in the atmosphere then more scattering takes place. Twilight observations have been carried out ma...
متن کاملInfluences of twilight on diurnal variation of core temperature, its nadir, and urinary 6-hydroxymelatonin sulfate during nocturnal sleep and morning drowsiness.
This study aimed at elucidating the physiological significance of dusk and dawn in the circadian rhythm of core temperature (T(core)) and urinary 6-hydroxymelatonin sulfate in humans during sleep and the waking sensation just after rising. Seven female and four male students served as participants. Participants retired at 2300 h and rose at 0700 h. They were requested to sit on a chair and spen...
متن کاملTheory of photometric errors applied to the design and evaluation of a high-performance filter photometer.
We have applied a comprehensive theory of photometric errors to the design and evaluation of an inexpensive stabilized photometer. The photometer is described in terms of a group of modules, the characteristics of which are described in terms of their effect on specific error coefficients. Procedures described in this paper show how the principles described earlier [Clin, Chem. 20, 1028 (1974)]...
