The total mass of the eroded atmosphere and of the retained vapor cloud, which is a function of atmospheric pressure and impact velocity, is written as the integral over impactor mass distribution.
Also, our simple model setting helps us to understand the physics which controls the induced flow and the mass of the eroded atmosphere and retained vapor cloud.
Then, the total blown-off mass is given, respectively, by the integration of the mass of the retained vapor cloud (mvap_ret) and the eroded atmosphere (matm_esc) over the impactor mass distribution, (23) and (24) where n (nimp, t) is the number of impacts between mimp and mimp + dmimp and given by (25).
Mars Express carried a colour stereo camera, an energetic neutral atoms analyzer to study how the solar wind erodes the atmosphere, a mineralogical mapping spectrometer, and atmospheric and radio science experiments.

How many people have been killed in this country this year by terrorism, compared with those killed in traffic accidents?" Her point was that it was important not to succumb to the kinds of security fears that could erode the atmosphere of public trust that has long been a cherished feature of British society, including its tradition of having unarmed policemen patrol its streets.
Proxima Centauri's flare outbursts could erode the atmosphere of any planet in its habitable zone, but the documentary's scientists thought that this obstacle could be overcome (see continued theories).
Chlorofluorocarbons, or CFC's, were also prized for their chemical stability until the 1970's, when scientists discovered that their accumulation in the atmosphere eroded the ozone layer.
A thicker atmosphere, less eroded by the solar wind, might have allowed large bodies of water to persist for long periods on or near the surface.That may have been enough for life to get started.
As a result light atoms experience high thermal escape rates and expand to large distances (Tian et al., 2008a, 2009) where the whole atmosphere may be eroded by solar/stellar wind plasma flow related non-thermal escape processes (Khodachenko et al., 2007; Lammer et al., 2007; Lundin et al., 2007; Lichtenegger et al., 2010).
However, in the case of molten material induced by a giant impact a major part of the atmosphere can be eroded and crustal formation may occur within only 1000 years (Lebrun et al. 2013; Solomatov 2007), possibly enabling the recording of the magnetic hemisphericity in the crust.
