Atmospheric cycling of gaseous selenium compounds: sources, transformations, and deposition

Figure 2. Seasonal distribution of global terrestrial biogenic Se emissions (μg Se·m-2·yr-1) estimated from the MEGAN-MACC inventory. The abbreviations denote the standard meteorological seasons: DJF (winter in the Northern Hemisphere), MAM (spring), JJA (summer), and SON (autumn). The emission maps are calculated by averaging monthly values over the available period (1980-2010) and are scaled so that total global emissions are 2.7 Gg Se·yr-1. Data were obtained from reference[37]. Se: Selenium; DJF: December-January-February; MAM: March-April-May; JJA: June-July-August; SON: September-October-November.
