Total energy radiated by an object of unit area per solid angle of measurement. The standard measurement unit is watts per square meter. This geometric radiation quantity is what is measured by remote sensing devices (Committee for Earth Observation Satellites).

| radiance |
A measure of the amount of electromagnetic radiation leaving a point on the surface. More precisely, it is the rate at which light energy is emitted in a particular direction per unit of projected surface area. The projected surface area is the projection of the surface onto the plane perpendicular to the direction of radiation. It is found by multiplying the surface area by , where is the angle of the radiated light to the surface normal.
