Net radiometers

Net radiometers are used to measure the radiation balance between incoming and outgoing radiation at the surface. They provide reliable data for meteorological monitoring, climate studies, and research on the energy balance of surfaces.

CNR4 - Net Radiometer

CNR4 - Net Radiometer

The CNR4 net radiometer is used to measure the radiation balance between incident and reflected short-wave radiation and long-wave infrared radiation. The instrument contains two pyranometers for measuring shortwave radiation and two pyrgeometers for measuring longwave radiation. The radiometer provides four separate outputs corresponding to the individual components of the radiation balance. This allows for the precise evaluation of the surface energy balance, albedo, or energy exchange processes between the surface and the atmosphere.

NR LITE2 – Net Radiometer

NR LITE2 – Net Radiometer

The NR LITE2 is a net radiometer designed to measure net radiation—that is, the difference between incident and reflected shortwave and longwave radiation. This parameter is key to determining the energy available for evaporation, photosynthesis, and surface–atmosphere heat exchange, and is essential in meteorology, agrometeorology, hydrology, and heat balance studies. The radiometer combines high sensitivity with a robust, weather-resistant design and is optimized for long-term outdoor measurements.
