Abstract We investigate the effect of varying biogenic surface emissions in investigate photochemical biomarker signals in the atmospheres of Superearths. Ozone for example is a good biomarker which is derived in-situ from the biomarker oxygen and which displays a strong spectral signal over a wide range of oxygen levels. However, responses of ozone photochemistry in Superearth environments are potentially complex, depending on the Chapman cycle producing ozone (sensitive to background pressure, temperature and photolysis rates) and catalytic cycles destroying ozone (sensitive to pressure-dependent reaction rates). We model a Superearth with only 20% increased mass compared with the Earth. This is a modest change because for a first analysis we wish to remain close to Earth conditions, for which our model has been validated. We analyse responses in the biomarkers ozone and nitrous oxide as well as the related compounds methane and water compared with the Earth control run.
