|Title:||Further Analysis of the vlf Atmospherics Data at Poona|
Puranik, G G
|Abstract:||Using the method of correlation coefficients the atmospherics data recorded at Poona simultaneously on 27, 10 and 1 kHz bands during the period June 1968 to October 1969, have been analyzed to study (i) the relationship between the hourly integrated intensities of these emissions and (ii) the variation of this relationship from month to month in each case. The most significant result is that almost all the monthly correlation coefficients as well as the total data period correlation coefficients are negative and significant. The total correlation coefficient values are in the following increasing order of magnitude. The period Feb.-Mar. 1969 showed a sharp transition from lower to higher monthly correlation coefficient values than the corresponding total values in all the three pairs of bands. Three regression equations between the pairs of monthly values have also been deduced which indicate, in a general way, that the 10 kHz band correlates well with both the other two bands which among themselves do not correlate in this manner. However, the present analysis is not penetrating enough to probe deeper into the nature of atmospherics Sources.|
