An attempt to correlate first mode Schumann resonance intensity with ground surface temperature at low latitudes

. Employing a system of 3-component search coil magnetometer installed in a remote area in the out skirt of Agra (Geographic lat.27.2 0 N, long.78 0 E), India, Schumann resonance (SR) observations have been in progress since 01 April, 2007. In this paper we analyze the first mode intensity data for a period of one year between 01 March, 2011 and 29 February, 2012 and correlate with ground surface temperature (GST) for low latitude region between ± 30 0 latitude.The GST data are taken from the website: http://www.tutiempo.net. Our results show that the variation curves of the two sets of data match satisfactorily with cross-correlation coefficient of 0.522 which is consistent with earlier workers for low latitude region. We also carry out linear regression analysis and regression equation is utilized to verify the calculated and measured GST which are found to be matching satisfactorily also.
