Study of Linke Turbidity Factor on Solar Radiation over Jumla
Keywords:air mass, clearness index, extinction coefficient, Linke turbidity, meteorological parameters
Population growth, mechanization, and industrialization are the by product of human civilization and its resultant impacts goes to degrade the natural environment by the affecting of air-pollution and also associated with climatic change. Linke turbidity factor (LT) is an important parameter for assessing the air pollution at Jumla (Lat.:29.28o N, Long.: 82.16o E and Alt. 2300 masl). Because of the unavailability of spectral measurements data , a model has been used to estimate the Linke turbidity factor (TL) from broadband measurement of Global Solar radiation in 2012 .The annual average solar insolation, clearness index (KT) and extinction coefficient (K) are 5.11 ±2.34kWh/m2/day ,0.71 ± 0.12 and 0.25 ± 0.13 respectively. Similarly, the annual average value of Linke turbidity factor (LT) and visibility 1.97± 0.47 and 28.09 ± 21.08 km are found. Finally it is found that there is strong relation between Linke turbidity factor and meteorological parameters i.e. relative humidity, temperature, water content, ozone and rain fall.
