Measurement of Ground surface temperature with Schumann resonance relation at Agra

Abstract

The relation between Schumann resonance (SR) intensity and ground surface temperature (GST) is studied at Agra region. For this purpose, SR intensity data observed at Agra (geographic lat.27.2oN, long.78oE) and GST data for the low latitude region from website: http://www.tutiempo.net/ are taken. The variations of average intensity and GST data over a period of one year from 01 April, 2007 to 31 March, 2008 are studied. It is seen that the variation curves for the two sets of data match satisfactorily and a cross-correlation coefficient of 0.4 is found which is consistent with earlier result for low latitude region. A linear regression analysis is carried out to find a link between the two and regression coefficients calculated. The regression equation is utilized to verify the calculated and measured GST which are found to match satisfactorily also. Here, we use this equation to calculate GST by substituting measured values of SR intensity and compute the unknown average ground surface temperature of Agra for the month of May, 2007 is found of 31.3 ⁰C.
