Fig. 3: Changes in peak summer NDVI and NDMI in peat areas between the early (1985–1995) and late periods (2005–2015 for High Arctic, 2010–2020 for Low Arctic), coloured by region.
From: Satellite data indicates recent Arctic peatland expansion with warming
A Temperature and Precipitation for the study sites from ERA5 reanalysis data (Hersbach et al.63), showing mean annual values (Mean Annual Temperature, Mean Annual Precipitation) for the early (lighter shaded) and late (darker shaded) periods, and seasonal mean change between early and late periods for the region means (grouped in 3-months periods). B change in mean NDMI (moisture) and mean NDVI (productivity) between early and late periods. C changes in areal distribution of NDMI and NDVI in peat-areas, with inset graphic to aid interpretation of the figure.
