Clouds in the atmospheres of extrasolar planets: IV. On the scattering greenhouse effect of CO2ice particles: Numerical radiative transfer studies
Open accessAbstract
Context. Owing to their wavelength-dependent absorption and scattering properties, clouds have a strong impact on the climate of planetary atmospheres. The potential greenhouse effect of CO2 ice clouds in the atmospheres of terrestrial extrasolar planets is of particular interest because it might influence the position and thus the extension of the outer boundary of the classic habitable zone around main sequence stars. Such a greenhouse effect, however, is a complicated function of the CO2 ice particles’ optical properties.

Recent multiple-stream scattering studies indicate that two-stream methods used previously to calculate CO2 cloud climate effects tend to overestimate the strength of the scattering greenhouse.
“In addition, recent multiple-stream scattering studies have indicated that the two-stream methods used previously to calculate CO 2 cloud climate effects tend to overestimate the strength of the scattering greenhouse (Kitzmann, Patzer & Rauer 2013).”

The warming effect of CO2 clouds on early Mars is likely to have been small in reality.
“Hence the warming effect of CO 2 clouds is likely to have been small in reality.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
