Laboratory validation of carbon-based aerosol warming for Mars

Demonstrate, via controlled laboratory experiments under Mars-relevant spectral and atmospheric conditions, the net radiative effect of carbon-based aerosols (e.g., nitrogen-doped graphene disks or ribbons), confirming that they produce net greenhouse warming without excessive solar attenuation.

Background

Engineered aerosols are proposed as a potentially mass-efficient way to augment Mars’ greenhouse effect. Modeling suggests certain carbon nanostructures resonate strongly at Mars-infrared wavelengths, but the overall net (warming) radiative effect has not yet been empirically validated.

This laboratory demonstration is a prerequisite for downselecting aerosol candidates and for assessing techno-economic feasibility and environmental safety.

References

The Mars-warming net radiative effect of carbon-based aerosol has not been demonstrated in the laboratory, although graphene disks and ribbons (size 0.25-1 μm) resonate strongly with Mars infrared radiation in experiments [20,93].
