irradiance
This term is a technical specification used primarily in physics, meteorology, and solar energy engineering. It describes the power of electromagnetic radiation per unit area, distinguishing it from "irradiant flux," which refers to the total power regardless of the surface area.
In professional contexts, it is almost exclusively used as an uncountable noun because it refers to a measurable physical quantity or a property of light. It is rarely pluralized unless referring to multiple distinct types or measurements of irradiance across different spectral bands.
Meanings
Examples
The sensor measures the total solar irradiance hitting the surface.
We need to calculate the spectral irradiance to understand the light distribution.
The peak irradiance occurs around noon when the sun is highest.
Check if the irradiance levels are consistent across the entire array.
I wonder if the cloud cover will significantly drop the irradiance today.
The study examines how varying irradiance affects plant growth rates.
The device is calibrated to detect minute changes in irradiance.
High irradiance can lead to overheating in some photovoltaic cells.
