What is Solar Spectral Irradiance (SSI)? (1 point)

A) the measure of the radiant energy emitted from the sun that reaches Earth’s atmosphere
B) the measure of the number of sunspots that appear on the sun during solar maximum
C) the measure of the amounts of different wavelengths of light in solar output
D) the measure of the amount of solar output that directly affects Earth’s climate

The solar spectral irradiance may be defined as the measure of the radiant energy emitted from the sun that reaches Earth’s atmosphere. Thus, the correct option is A.

What is Radiant energy?

Radiant energy may be defined as the physical energy that results from electromagnetic radiation of the sun usually observed as it radiates from a source into the surrounding environment.

The solar Spectral Irradiance (SSI) illustrates the actual radiation that is emitted by the sun and finally reaches and falls on the earth's surface without any deflection in its intensity.

This irradiance actually estimates the level and intensity of brightness of the entire sun at a particular wavelength of light.

Therefore, the solar spectral irradiance may be defined as the measure of the radiant energy emitted from the sun that reaches Earth’s atmosphere. Thus, the correct option is A.
