Vegetation dynamics at field sites in the sandy Ferlo (1987–2016). a Matrix showing the Pearson correlation coefficient between different satellite datasets (p90 and p30) with total green vegetation mass (AGH + WPF), as well as herbaceous (AGH) and woody foliage (WPF) mass separately (n = 30). The highest correlations of each row are marked with a red square. Both the colour and the filling of the circle show the strength of the correlations. P90 is located during the wet season when both woody and herbaceous plants have green leaves, p30 is located in the dry season when only woody plants have green foliage (Supplementary Fig. 2). b P90 satellite observations and total green vegetation mass (AGH + WPF). The annual values have been standardised by the mean and standard deviation (z-score). Note that the lengths of the time series differ (see Supplementary Table 1). Parts of the legend is shared with (d). c Field-measured AGH and WPF in kg ha−1. d Field-measured AGH and p90–p30 satellite observations. e The contribution of field-measured AGH and WPF to the total vegetation mass. f Field-measured WPF and p30 (p10 for L-VOD) satellite data for Ferlo. All pixels overlaying the nine field sites are averaged per year and satellite product for 1987–2016. Error bars are the standard deviations between the field data plots
