BackForward Variable: Cosmic ray neutron flux

Definition
Full name Cosmic ray neutron flux
Definition Flux of neutrons near the surface of Earth due to collisions in the atmosphere of cosmic rays impacting Earth atmosphere from the Sun and outer space.
Measuring Units neutrons·h-1 Uncertainty Units %
Horizontal Res Units km Vertical Res Units
Stability Units % (Stability /decade)

 

Comment: A proxy of the high energy radiation striking Earth atmosphere from space. The neutron monitors counting rates (sensitive to the low energy portion of the spectrum, 1-20 Gev) should be corrected for atmospheric pressure effects. For ground level energetic particle detection. Note hat the horizontal resolution varies with latitude and longitude. Higher resolution is needed in latitude, in particular at high to middle latitudes where the cut-off boundary exists for incident particles.
