NR Lite Allwave Net Radiometer

The NR-LITE is a high-output thermopile sensor which measures the algebraic sum of incoming and outgoing all-wave radiation (i.e. both short-wave and long-wave components). Incoming radiation consists of direct (beam) and diffuse solar radiation plus long-wave iradiance from the sky. Outgoing radiation consists of reflected solar radiation plus the terrestrial long-wave component. The NR-LITE is equipped with Teflon-coated sensor surfaces. This results in a robust design which allows for very easy maintenance and good sensor stability.
