Figure 1: 15-year (2000–2014) trends of annual GPP and the three indicators in North America.

From: Dominant role of plant physiology in trend and variability of gross primary productivity in North America

Figure 1

(a) Annual GPP. (b) Start of growing season (GSstart). (c) Maximum daily GPP (GPPmax). (d) End of growing season (GSend). A negative sign (red color) in (b) and (d) denotes an earlier trend of GSstart and GSend, and vice versa. Maps were generated using MATLAB 2015b (http://www.mathworks.com/products/matlab/).
