Seasonal variation of the relevant meteorological variables with the vegetation growth from 1st July 2008 to 31st December 2009 at both sites: daily averages of a leaf area index (LAI), b vapor pressure deficit (VPD), air temperature (T _A), c photosynthetic photon flux density (Q) and light index (K), and d precipitation and soil water content (SWC) at 10 cm depth. Forest (black color) and savannah (gray color). The vertical pink discontinuous line indicates the periods I to IV
