Daily estimates of morning and afternoon mixing depths, average wind speeds through mixing layer and ventilation coefficient during clear winter months (Octcber-March) from 1970. 1977 were calculated and monthly averages of these parameters for 7 years are presented and discussed. Daily estimates or ground inversions laps rate, mean Wind through the inversion heights and their thickness were calculated from 1968 to 1977. Percentage frequency of ground based inversions of different height and wind speed ranges based on 00 and 12 GMT ascents for 10 years are also presented . Monthly percentage frequency and strength of inversions, their thickness averaged over 10 years is also depicted. Comparison or mversrons at Delhi and Math ura are also made.
