Explanation:
pyrheliometer
Direct solar radiation is measured using a pyrheliometer, an instrument that directly measures solar irradiance. The field of view of this instrument is limited to 5°. Global radiation is the sum total of direct solar radiation and diffuse sky radiation received by a horizontal surface per unit area.
