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.
