Radio waves reflecting back to Earth from the ionosphere, one of the
regions of the upper atmosphere, can offer valuable news on climate
change, according to new research from Tel Aviv University.
It is already known that the ionosphere plays an important role in
global communications. Ionized by solar radiation, this electricity-rich
region is used for the transmission of long wave communications, such
as radio waves.
Now Prof. Colin Price
of Tel Aviv University’s Department of Geophysical, Atmospheric and
Planetary Sciences, working alongside PhD candidate Israel Silber, says
that the strength of radio signals on the ground is a reliable indicator
of temperature change above.
