Results of the study of seasonal variation of total column content of aerosols in the 50—1100 m heightregion are presented,The columnar content of aerosols is computed by integrating the height profiles ofnighttime aerosol number density estimated from the Argon ion lidar observations collected at the ⅡTM,Pune for the one year period from October 1986 to September 1987.The results of the study indicated thatthe aerosol content was higher during winter than during monsoon months by over 78% with an annualmean columnar aerosol content of 1.66×10~8 cm~(-2).The observed seasonal variaticn of aerosol content wasfound to be associated with that of surface wind,temperature,relative humidity(R.H.)and rainfall datarecorded for the above one year period at the station.
