During this time, the sun shines for 24 hours each day. In 2018, growing season conditions and tundra productivity contrasted starkly between North America and Eurasia. NDVI in the Eurasian Arctic was similar to the previous year, but declined sharply in the North American Arctic (Fig. 2a,b), much of which experienced late snowmelt and relatively cool summer temperatures (Mudryk et al. 2018; Schmidt et al.
