The Variation of the Atmospheric Potential Gradient cau ed by the Smoke of the Locomotive Engines

[摘要] The variation of the atmospheric potential gradient caused by the smoke of the locomotive engines was recorded at the Kuts_??_kake Railway Station and at the Kar_??_izawa Meteorological Station (about 400m from the railway). It is almost always positive and reaches to about 2, 000V/m at the railway station and about 300V/m at the meteorological station The density of the space charge in the smoke is about 5esu/m3 at the distance of 50m from the locomotive and about 0.05esu/m3 at the meterological station.
