Instrument: Eppley Longwave Radiometer

Acronym: Eppley PIR
External Identifier: skos:closeMatch: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0083/

Description

The Eppley Precision Infrared Radiometer (PIR) pyrgeometer measures longwave (infrared) radiation. It is housed in a weatherproof titanium canister that has been painted with a very flat black paint that absorbs radiation. A small glass dome at the top of the instrument is covered with an 'interference coating' which allows only infrared radiation to come through. Light levels are detected as temperature changes creating voltages in fine wire coil detectors. more from Eppley Labs
