Subset of the Finnish pulsation magnetometer data from Nurmijärvi 27.9.2001 and 1.10.2001

This induction coil data set used in paper "Characteristics of magnetic fields at frequencies (0.1-20) Hz in Earth-Ionosphere Waveguide with 3D Inhomogeneous upper wall" by E.N. Ermakova, D.S. Kotik, and A.V. Ryabov. Same data set used also in Ermakova, E. N., D. S. Kotik, S. V. Polyakov, T. Bösinger, and L. A. Sobchakov (2006), A power line as a tunableULF-wave radiator: Properties of artificial signal at distances of 200 to 1000 km, J. Geophys. Res., 111, A04305,doi:10.1029/2005JA011420 and in Ermakova, E. N., D. S. Kotik, S. V. Polyakov, T. Bösinger, and L. A. Sobchakov (2006), A power line as a tunableULF-wave radiator: Properties of artificial signal at distances of 200 to 1000 km, J. Geophys. Res., 111, A04305,doi:10.1029/2005JA011420.
