Table 1 Model simulations and corresponding prescribed isoprene emissions
From: Atmospheric isoprene measurements reveal larger-than-expected Southern Ocean emissions
Simulation | Isoprene emissions | Ratio of simulated / observed Isop concentration (\({{{{{\rm{median}}}}}}_{25{{{{{\rm{th}}}}}}\; {{{{{\rm{percentile}}}}}}}^{75{{{{{\rm{th}}}}}}\; {{{{{\rm{percentile}}}}}}}\)) |
|---|---|---|
TI_base | Terrestrial only | \( < 1{0}^{-9}\) |
TI_2x_30S | Terrestrial only with emissions below 30°S doubled. | \( < 1{0}^{-9}\) |
TI_MI_MEAN | Terrestrial emissions and marine emissions calculated following ISOREMS parameterisation12 | \({0.025}_{0.008}^{0.062}\) |
TI_MI_20x | As TI_MI_MEAN but marine emissions scaled by 20. | \({0.490}_{0.166}^{1.153}\) |
TI_MI_MEAN_D | As TI_MI_MEAN but with a diurnal scaling applied to marine isoprene emissions. | \({0.019}_{0.006}^{0.046}\) |
TI_MI_20x_D | As TI_MI_20x but with a diurnal scaling applied to marine isoprene emissions. | \({0.368}_{0.146}^{0.838}\) |
TI_MI_MEAN_D_sink | As TI_MI_MEAN_D with an extra species, “OH-sink”, which has (non-diurnally varying) emissions equal to those of marine isoprene. OH-sink has a rate constant half that of isoprene + OH and does not regenerate any OH. | \({0.018}_{0.006}^{0.045}\) |
TI_MI_MEAN_D_sink_100x | As TI_MI_MEAN_D_sink but OH-sink emissions are 100x those of marine isoprene. | \({0.021}_{0.008}^{0.053}\) |
