ARLA/CLUSTER: Os maciços bombardeamentos aliados durante a Segunda Guerra Mundial alteraram a ionosfera

[João Costa > CT1FBF]

Allied bombing in WW2 altered ionosphere

Research by *Professor Chris Scott*, from the University of Reading, shows
the impact on the Ionosphere of the Allied bombing raids over Europe during
WW2

Chris says
*"Each raid released the energy of at least 300 lightning strikes."*
Researchers studied daily records kept at the Radio Research Centre in
Slough, UK. They looked at how the concentration of electrons changed in
the upper atmosphere around the time of 152 Allied air raids in Europe.

The data showed the concentration of electrons fell significantly when a
bomb was detonated, which in turn heated the upper atmosphere. This caused
a small but significant depletion in the ionosphere above Slough, even
though the bombs were deployed hundreds of miles away.

In his paper, the contribution of ground-based disturbances to ionospheric
variability is investigated by considering the response of the ionospheric
F2 layer over Slough, UK, to 152 major bombing raids over Europe during
World War II. Download PDF from
