Pyrgeometers / Four-Component Radiometer

EKO Instruments Co., Ltd. (EKO)

EKO's pyrgeometers and net radiometers are used for meteorological observations of atmospheric radiations (radiations from clouds, water vapor, CO2 etc.) and the net radiation exchange between the earth and the atmosphere. Net total irradiance (shortwave + longwave) is typically measured by 4 component net radiometers or single component pyradiometers which have a single detector covering the full range. Pyrgeometers measure the long wave down welling radiation by means of a single detector facing the atmosphere. The Net longwave and down welling radiation can be determined by calculation.
