Enhanced heating of the stratosphere could be behind the heightened effects felt by Europe of changes in solar activity.
Researchers have long known that greenhouse gases might help the layer recover by cooling the stratosphere, which slows the rates of chemical reactions that destroy ozone.
The findings will trigger a radical rethink about the state of the stratosphere.
OMI allows scientists to assess how much ozone is present at various altitudes—particularly the stratosphere—and near the ground.
Directly behind the shuttle is the mesosphere, which appears blue. The atmospheric layer that appears white is the stratosphere, while the orange layer is Earth's Troposphere.
At other times, though, they have seemed to predict a wetter stratosphere.
Volcanoes inject sulphur dioxide into the stratosphere, where it eventually forms small particles of sulphate that reflect sunlight back into space.
This is because the top of the troposphere is normally very cold, causing ascending water vapour to freeze into ice crystals that drift and fall, rather than continuing up into the stratosphere.
The stratosphere, the part of the Earth's atmosphere which does most to absorb UV, might thus be expected to be particularly sensitive to the cycle.
Wake turbulence between the two aircraft as well as engine performance and flight control responsiveness in the stratosphere were evaluated.
Vicious cycle: Water in the stratosphere contributes to the current warming of the earth's atmosphere.
That in turn may increase the severity of tropical cyclones, which throw more water into the stratosphere.
The pink to white region above the clouds appears to be the stratosphere; this atmospheric layer generally has little or no clouds and extends up to approximately 50 km above the Earth’s surface.
In the week of the Asilomar meeting Science published evidence that more pollutants than previously appreciated, including oxides of sulphur, are getting into the lower stratosphere.
