As a part of the joint efforts of operating six meridian chains of magnetometers during the IMS, magnetic records from 71 stations are used to deduce the distribution of electric fields and currents in the polar ionosphere for March 17, 18, and 19, 1978. As a continuation of this project, we have constructed hourly distribution maps of the Joule heat production rate and their sum over the entire polar region on the three days. For this purpose the conductivity distribution is inferred at each instant partially on the basis of an empirical method devised by Ahn et al. (1982). The particle energy injection rate is estimated similarly by using an empirical method. The data set thus obtained allows us to estimate also the global Joule heat production rate UJ, the global particle energy injection rate UA and the sum U&Ggr; of the two quantities. It is found that three global quantities (watt) are related almost linearly to the AE(nT) and AL(nT) indices. Our present estimates give the following relationships: UJ=2.3 times 108 ⋅ AE8 UA=0.6 times 108 ⋅ AE8 and UI=2.9 times 108 ⋅ AE: UJ=3.0 times 108 ⋅ AL8 UA=0.8 times 108 ⋅ AL, and UI=3.8 times 108 ⋅ AL.
