Figure S1: Profiles of the net radiative flux [W m-2] for six fluorinated species, in the
Line-By-Line Radiative Transfer Model (LBLRTM; solid lines) and in the rapid radiative
transfer model (RRTMG; dashed lines), based on profiles of each species’ maximum
expected concentrations.

Figure S2: Scatter plot of the 2050 surface radiative forcing, the product of an HFC
species’ surface mixing ratio and its radiative efficiency, with respect to the simulated
total column ozone loss (circles, DU) and temperature response in the 10-25 km layer
(squares, K). Note that the simulated atmospheric responses are proportional to the
magnitude of the surface radiative forcing.
The shapes with black outlines show
responses based on the Velders et al. [2009] high scenario and Miller and Kuijpers [2011]
business-as-usual scenario; the yellow shapes with red outlines show the HFC-125
responses based on the Velders et al. [2009] low scenario.

Figure S3: Upper panel: Projected global mean surface mixing ratios for five HFC
species (yellow-orange shading, ppbv) and the total for five HFCs (gray shading). Lines
with higher mixing ratios denote values from the Velders et al. [2009] high scenario and
Miller and Kuijpers [2011] business-as-usual scenario; lines with relatively lower mixing
ratios denote values from the Velders et al. [2009] low scenario and Miller and Kuijpers
[2011] best practices scenario.

to all five HFCs simultaneously; lines denote responses in the two sets of HFC scenarios.
Lower panel: Same as for the center panel, but for the modeled global mean total ozone
response (DU, %). The total column ozone timeseries are smoothed to emphasize the
long-term ozone trends.
