From: Seasonal variation in net ecosystem CO2 exchange of a Brazilian seasonally dry tropical forest
Heat map based on correlation matrix between net ecosystem CO2 exchange (NEE) gross primary production (GPP), ecosystem respiration (Reco), air temperature (Ta), soil temperature (Ts), vapor pressure deficit (VPD), relative humidity (RH), global radiation (Rg) for the wet season (A,B, respectively) and dry season (C,D, respectively) of 2014 and 2015 in the Caatinga (ESEC-Seridó). Warm colors represent positive correlation and cool colors represent negative correlation based on Pearson’s correlation test (p < 0.05).
