Parameter: Potential drop across polar cap

Brief Description:
Simple linear relationships are given for the dependence of the potential drop across the polar cap on interplanetary parameters. The linear regression parameters are obtained by least-square fits to AE-C, AE-D, and S3-3 satellite data. Parameters are listed for the dependence on a variety of interplanetary parameters, including the solar wind velocity and the interplanetary magnetic field components. Variation with Kp is given by Senior et al. (1990).
