The CGR4 is a pyrgeometer, designed for top level solar radiation monitoring networks such as the Baseline Surface Radiation Network (BSRN) of the World Meteorological Organisation for the meteorological measurements of downward atmospheric longwave radiation. The CGR4 uses a thermopile detectors and has a sensitivity of 5 to 15V/W/m in a spectral range of 4.5 to 42m. This pyrgeometer has a specially designed silicon meniscus dome with a hard-carbon coating for a smooth spectral response ...

The NR Lite2 is a single component net radiometer used for monitoring the difference in incoming radiation from the Sun and sky and outgoing radiation from the ground. The NR Lite2 uses a double-sided thermopile detector fitted with black PTFE coated conical absorbers with a single output for the net radiation. The sensor covers a very wide spectral response from the Ultraviolet (UV) to far infrared (FIR). The NR Lite2 has an integral mounting rod ...

The CNR4 net radiometer integrated 4 solar sensors into a single instrument body. The CNR4 consists of a pair of pyranometers and a pair of pyrgeometers. Each pair has one facing upwards for incoming radiation and one facing downwards for the outgoing radiation. The CNR4 has four separate output signals from the sensors, plus integrated temperature outputs. The signal outputs represent the incoming and outgoing short-wave (Solar) and long-wave (atmospheric and terrestrial) radiation, whilst the ...
