Figure 3.9 Regionally-averaged annual snow-cover duration (SCD) series over the North American Arctic north of 66°N (anomalies with respect to a 1971–2000 reference period) from 20 climate stations in the Global Historical Climate Network archive with ≥40 years of daily snow depth data in the 1950/51–2013/14 snow seasons. A 1971–2000 reference period was used to maximize the number of stations in the regional average. The trend over the period (-4.4 days per decade) is statistically significant at the 0.05 level.
