ARLA/CLUSTER: Radiação cósmica está a aumentar

Atmospheric radiation is increasing

New space weather balloon measurements over California show that
cosmic rays in Earth's atmosphere are increasing. The main reason is
the solar cycle.

In recent years, sunspot counts have plummeted as the sun's magnetic
field weakens. This has allowed more cosmic rays from deep space to
penetrate the solar system and, in turn, our planet's atmosphere.

An interesting anomaly occurred in Sept. 2017 when a sudden outburst
of solar activity pushed cosmic rays away from Earth, causing a
temporary dip in the radiation field.
