(a,b) GSstart and preseason (30 days before the mean date of GSstart) temperature. (c, d) GPPmax and summer temperature (mean temperature in June-July-August). (e,f) GSend and preseason (30 days before the mean date of GSend) temperature. Maps were generated using MATLAB 2016a (http://www.mathworks.com/products/matlab/).
