Paper Abstract

In this paper we show changes in the dates of snow disappearance in the Arctic between the late 1960s and the early 2000s, from arbitrary but consistent boundaries, using National Oceanic Atmospheric and Administration (NOAA) satellite observations. The date the snowline retreats during the spring (when it first moves north of the 60° and 70° parallels) has occurred approximately a week earlier in recent decades compared to the late 1960s, for many Arctic locations. During this same period, substantial portions of the Arctic have been experiencing higher temperatures and a conspicuous diminution of sea ice, especially in the past 10 years. Our results generally agree with these observations -- tendency toward earlier snowmelt was sustained until about 1990. Since that time, however, the date of snow disappearance has not been occurring noticeably earlier, and snow cover has actually been forming earlier in the autumn.
