CR+cosmic+ray+research+question

Does the distance to the equator have any effect on the influx of cosmic rays? I am not sure but what I am more interested in is whether or not the longitude or the horizontal distance of the detector has any effect on the influx or detection of cosmic rays.

I propose to take the flux data of 6 detectors on the upper west coast and 6 detectors on the upper east coast and compare the data to determine whether or not the difference in longitude has any effect on the flux data.
