Figure 2: Results of the breakpoint analysis for Hesse.
From: Remotely-sensed detection of effects of extreme droughts on gross primary production
Seasonally adjusted data (abbreviated as ‘ad.’ in axis labels) are shown for the 8-day products of (a) MODIS GPP product (modGPP), (b) NDVI, (c) EVI, (d) EVI2, and (e) standardized Photochemical Reflectance Index (sPRI). For sPRI normalized for APAR (sPRIn; panel f), the absolute values are shown because no seasonal pattern was detected by sPRIn (see SI). The grey area indicates the drought episode. The black lines indicate the results of the breakpoint analysis.
