Visão Geral
The CNR1 net radiometer by Kipp & Zonen is for applications requiring research-grade performance. The radiometer measures the energy balance between incoming short-wave and long-wave IR radiation versus surface-reflected short-wave and outgoing long-wave IR radiation. The CNR1 consists of a pyranometer and pyrgeometer pair that faces upward and a complementary pair that faces downward. The pyranometers and pyrgeometers measure short-wave and far infrared radiation, respectively. The CNR1 also includes an RTD to measure the radiometer’s internal temperature and a heater that can be used to prevent condensation. Lead length is 82 ft. For custom cable length, order CNR1-L.

Descrição Técnica
The CNR1 comes with an 82-ft cable length. This net radiometer is for applications requiring research-grade performance. It measures the energy balance between incoming short-wave and long-wave infrared radiation versus surface-reflected short-wave and outgoing long-wave infrared radiation.
The CNR1 consists of a pyranometer and pyrgeometer pair that faces upward and a complementary pair that faces downward. The pyranometers and pyrgeometers measure short-wave and far infrared radiation, respectively. All four sensors are calibrated to an identical sensitivity coefficient.
The CNR1 also includes an RTD to measure the radiometer’s internal temperature, a 4WPB100 module to interface the RTD with the data logger, and a heater that can be used to prevent condensation.
The CNR1 uses six differential or four single-ended and two differential analog channels on the data logger. Data loggers that provide sufficient channels include our CR1000, CR3000, and CR5000.

If the BR (Bowen Ratio) system is being run on 21X or CR23X dataloggers, a CNR1 net radiometer cannot be used with the system because those data loggers do not have enough input channels. For this reason, Campbell Scientific recommends running a CNR1 out of a separate data logger.

CNR1 is a four-output net radiometer. It gives values for incoming short-wave, incoming long-wave, outgoing short-wave, and outgoing long-wave radiation. It also calculates the net radiation and albedo.
