According to a new study, the gradual increase of water vapour
in the air owing to daily human activities is playing a huge role in making these shimmering night clouds appear more visible.

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.
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
Versaperm has introduced a version of its Water Vapour
Transmission Meter (WVTR) that can not only measure the water vapour
permeability of packaging, but can be configured to measure permeability for a wide range of other gases as well.
An international team of scientists, including researchers from University College London, found water vapour
on a planet called HD189733b.
The water vapour
(sweat) resistance of fabrics has been measured using the sweating guarded hotplate.
