A long-term Arctic snow depth record from Abisko, northern Sweden, 1913–2004
A newly digitized record of snow depth from the Abisko Scientifi c Research Station in northern Sweden covers the period 1913–present. Mean snow depths were taken from paper records of measurements made on a profi le comprising 10 permanent stakes. This long-term record yields snow depths consistent...
