Record #197506:

Geomagnetic activity at the Sodankylä observatory, 1914-2010 / Heikki Nevanlinna, Lasse Häkkinen, Tero Raita.

Title: Geomagnetic activity at the Sodankylä observatory, 1914-2010 / Heikki Nevanlinna, Lasse Häkkinen, Tero Raita.
Author(s): Nevanlinna, Heikki.
Häkkinen, Lasse.
Raita, Tero.
Date: 2011.
In: Geophysica. (2011.), Vol. 47(1-2) (2011)
Abstract: Analyzes variations in space weather conditions at Sodankylä observatory (67.4°N, 26.6°E) since 1914, using magnetic activity index series consisting of daily Ak-numbers. Presents comparison of differences between manually-derived K-index numbers and those calculated by algorithm developed at Finnish Meteorological Institute.
