Pyrgeometer

The pyrgeometer is a sensor of atmospheric radiation. It is a hemispherical radiometer used to measure the incident infrared radiative flux on the surface of the Earth in all directions (solid angle of 2∏) and due to long wave radiation from the atmosphere or that emitted and reflected by the ground.
