Equivalent stratospheric chorine (ESC) concentrations, 1960 to 2100

Equivalent stratospheric chloric (ESC) concentrations with projections to 2100 based on chemistry-climate models. ESC concentrations are measured relative to levels
in 1960 (1960 = 0), and measured as the global average, and regional average. Figures represent the mean across a number of model runs; model projections have
notable uncertainty around such average trends.
