BackForward Variable: Solar X-ray flux

Definition
Full name Solar X-ray flux
Definition Integrated X-ray flux over the solar disk
Measuring Units watt·m-2 Uncertainty Units watt·m-2
Horizontal Res Units Vertical Res Units
Stability Units watt·m-2 (Stability /decade)

 

Comment: Typical measurements include the 0.1-0.8 nm and the 0.05-0.4 nm wavelength bands. Used to track solar eruptions and estimate ionospheric radio absorption.
