Abstract


Background/Objectives: The assessment of turbulence parameters is important for understanding the heat, momentum exchange and pollutant dispersion at any given site. Methods/Analysis: Continuous micrometeorological data were collected at SRM University, Kattankulathur (12o 48’ N to 12o 49’ N; 80o 02’ E to 80o 03’ E) a sub-urban area near Chennai by a 16 m meteorological mast. Data with conventional sensors were obtained for wind, temperature, and humidity from August 2010 to March 2015. Findings: The gradient observations were analyzed to explore the atmospheric surface layer parameters and were used in atmospheric dispersion modeling. Wind and temperature data were analyzed to understand their diurnal and seasonal variations. The Inter-relationships of temperature and wind pattern were discussed and the diurnal variations of temperature and wind profile were plotted for a particular month during study period to assess the Climate pattern ofa particular study period. This study may play a vital role in atmospheric modeling and also in space vehicle launching.

Keywords
