Monthly values of a photosynthetically active radiation (PAR) and vapor pressure deficit (VPD), b mean air temperature (Ta) and total precipitation (PPT), and c soil Relative Extractable Water (REW) in the 0–30 cm soil layer at each site. Dry years are shaded as yellow (2007, 2017), hot year is shaded as orange (2018), and concurrent hot and dry years are shaded as red (2005, 2010, 2012 and 2016)
