A new radiometer for atmospheric long waves

A new radiometer has been designed which employs a black plate whose radiation towards the night sky is balanced by infrared radiation transferred in vacuo. The instrumental characteristics are described by a simplified theory and by laboratory tests making use of large surfaces with known emissivities. The instrument allows ‘the incoming’ IR atmospheric flux to be measured with a high degree of accuracy and independently of the ventilation rate.
