The most common application is the measurement of Net (total) Radiation at the earth's surface. 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 In particular, the CNR1 net radiometer measures: - incoming shortwave radiation -outcoming shortwave radiation -incoming longwave radiation - outcoming longwave radiation - net radiation (derived) Ev-K2-CNR +39 035 3230511 +39 035 3230551 Via San Bernardino 145 Bergamo BG 24126 Italy evk2cnr@evk2cnr.org http://www.evk2cnr.org/ https://geoportal.mountaingenius.org/geonetwork/srv/api/records/6b6981c1-1d45-4ad0-9033-ed1d89642c71/attachments/evk2cnr__.png evk2cnr__.png https://geoportal.mountaingenius.org/geonetwork/srv/api/records/6b6981c1-1d45-4ad0-9033-ed1d89642c71/attachments/evk2cnr__.png evk2cnr__.png SHARE Network Station High Altitude CEOP Lukla Nepal Khumbu Valley Sagarmatha National Park AWS global radiation No conditions apply climatologyMeteorologyAtmosphere environment geoscientificInformation 80.0522 88.1946 26.3684 30.4247 https://geoportal.mountaingenius.org/geonetwork/srv/api/records/6b6981c1-1d45-4ad0-9033-ed1d89642c71/attachments/Data%20Usage%20Policy.pdf WWW:DOWNLOAD-1.0-http--download http://www.eol.ucar.edu/projects/ceop/dm/insitu/sites/ceop_ap/Himalayas/Lukla/ WWW:LINK-1.0-http--partners Himalayas Reference Site Lukla Station Instruments: AWS sensors 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.
