Together with his colleagues, the researcher has investigated a large number of MOFs and identified those which are particularly stable with respect to water vapour. Instead of the previous 0.4, these can absorb up to 1.4 grams of water per gram of material.
Although the GNSS tomographic technique has limitations, especially the necessity of a dense distribution of stations to provide a large set of observations in a confined area to avoid a negative impact of the noising in the solution reconstruction of the water vapour images (Champollion et al., 2005; Bender et al., 2011; Rohm, 2013; Shangguan et al., 2013).
Lorenz Roth, from the Southwest Research Institute in San Antonio, Texas, said: "The discovery that water vapour is ejected near the south pole strengthens Europa's position as the top candidate for potential habitability.
Air can contain varying amounts of water vapour; warm air can hold more water vapour than cold air.
The integrity of this extremely thin metal layer is found to provide an excellent barrier to light, water vapour, oxygen as well as other gases and aromas.
They found that without the sustaining support of these gases, the greenhouse effect rapidly collapsed as water vapour precipitated out of the atmosphere, and the Earth became icebound.
If the fan did not run you would need to increase the heating to drive out the water vapour instead.
