In a quest to better predict space weather, the Dartmouth researchers study the radiation belts from above and below in complementary approaches — through satellites (the twin NASA Van Allen Probes) high over Earth and through dozens of instrument - laden balloons (BARREL, or Balloon Array for Radiation belt Relativistic Electron Losses) at lower altitudes to assess the particles that rain down.

In November, the spacecraft will swoop low over the surface at an altitude of just several kilometers and drop the Philae lander, which will sample the comet — if the lander's two harpoons can keep it stuck to the surface.

Because the vast plateau at such altitudes absorbs a huge amount of solar radiation, the atmospheric layer above it in summer is much warmer than air at similar elevations over lower land or the oceans.

The lower edge of the stratosphere, bounded by the tropopause, varies in altitude from about 18 kilometres at the equator to between 6 and 8 kilometres over the poles.

The sea ice in the Siberian Arctic is peaking, its effect on the meridional temperature gradient strong, promoting increased zonal flow of large - scale winds, which advect warm air and moisture over the Eurasian continent from the Atlantic and disrupt vertical stratification near the surface and promote high cloudiness, both of which lead to increasing temperatures — greatest at low altitudes and high latitudes.
