The Pierre Auger Collaboration measured a dipolar anisotropy in the arrival-direction distribution of the cosmic rays with energies in excess of 8x1018 eV, finding that the flux is about
6.5% larger than the average in one direction of the sky and it is correspondingly smaller in the opposite direction.
Extensive air showers, initiated in the Earth’s atmosphere by high-energy cosmic rays, emit pulsed radio signals with a typical duration of tens of nanoseconds.
