This is a directional quantity. This is sometimes also confusingly called "intensity". Radiance of a surface per unit frequency or wavelength. The latter is commonly measured in W⋅sr −1 ⋅m −2 ⋅nm −1. To relate this to the spectral irradiance at the earth: Irradiance is radiance per steradian. So you have to multiply the radiance by the solid angle subtended by the sun at the earth, 6.87 × 10−5 6.87 × 10 − 5 sr. Next, you calculation is in terms of the wavelength interval in meters. You have to convert that to nm.

A solid angle, ω, made up of all the lines from a closed curve meeting at a vertex, is defined by the surface area of a sphere subtended by the lines and by the radius of that sphere, as shown below.

The first two statements form the basis for declaring plane and solid angles as dimensionless quantities, and their units (radian and steradian) - as dimensionless number 1. The latter statement served as the basis for transferring the radian and the steradian into a class of derived units. We will analyze the validity of these statements.In the International System of Units (SI), a solid angle is expressed in a dimensionless unit called a steradian (symbol: sr). One steradian corresponds to one unit of area on the unit sphere surrounding the apex, so an object that blocks all rays from the apex would cover a number of steradians equal to the total surface area of the unit sphere, .
