Remotely sensed soil moisture to estimate savannah NDVI
Fig 2
Correlation (r) between soil moisture modelled NDVI and MODIS-NDVI.
Left: Distribution shown for all significant pixels. The few values below zero omitted for visual purposes. Right: Heat-map of the average correlation for each dataset used to model NDVI which has been divided into aridity classes; arid (0.03 < AI < 0.2), semi-arid (0.2 < AI < 0.5), dry sub-humid (0.5 < AI < 0.65), and humid (AI > 0.65). Average correlation values shown within heat-map grid.
