Service S2: Arctic-alpine growing season mapping serviceThe Arctic-Alpine Growing Season service will provide a service for mapping the onset, peak, and end of the growing season in selected areas of the arctic and alpine parts of northernmost Europe.
Promoting Earth Observation Services
- changes in the growing season are among the best bio-indicator of changes in
climate in Arctic and alpine areas
- it is the first indication of changes in the vegetation cover
- it is important for the feedback loop to the climate system
- it highly influence the population size of most birds, animals, and insects

Simulated Sentinel-2 data
- Time-series of interpolated cloud-free mosaics of MODIS data
for the period 2000 – 2012
- Time-series of Landsat 8 data from 2013 (2014). Almost daily
data from high arctic areas

Two study sites
1) Svalbard (mask out glaciers and non-
vegetated areas)
2) Northern Fennoscandia (mask
out forests and non- vegetated areas)
Three Sentinel-2 based products:
P2.1 Onset of the growing season
P2.2 Peak of the growing season
P2.3 End of the growing season
