Quiet day curve for RIOMETERs: Analysis and comparison of methods

The RIOMETER is a passive instrument that measures the intensity of the cosmic signal that reaches the Earth's surface. With the adequate analysis of this signal, it is possible to determine the attenuation suffered by them, when traveling through the ionosphere, particularly at the altitudes o...

description The RIOMETER is a passive instrument that measures the intensity of the cosmic signal that reaches the Earth's surface.
