Typical NDVI time series for selected pixels in the study area: (a) on Oldoinyo Lengai, (b) in the ash affected zone, (c) in the Crater Highland forest, (d) in the savannah. The original NDVI and the NDVIcorr after TIMESAT correction are shown for each pixel from May 2005 to May 2013. (e) Interpolated rainfall time series from May 2005 to May 2010. Note the grey shading highlighting the eruption period. f: NDVI image of study area in February 2008 with location of pixels analysed in A-D
