Abstract
The temperature structure parameter at Delhi has been determined from intensity information of sodar observations for a period of one year at a height of 200 m in the planetary boundary layer applying the moisture correction due to Wesely. It is found that mean monthly values of the temperature structure parameter for stable and unstable conditions are quite different during the monsoon months (July to October) but are rather similar during the other months.
The refractive index structure parameter values have been calculated for the dry atmosphere (optical) as well as by applying the moisture correction (radio) due to the Sirkis and Ottersten et al. models. It is found that the dry atmospheric values of the parameter are generally lower than the humidity-corrected values. The sodar-measured values of the parameter under dry atmospheric conditions have been examined in relation to the Hufnagel and Tsvang models.
