Zusammenfassung Ground-based, low-uncertainty measurements of the hemispherical long-wave downward radiation, which are strongly connected to the greenhouse effect of the earth, are performed globally with pyrgeometers and for example within the Baseline Surface Radiation Network (BSRN). To achieve low measurement uncertainties, highly accurate detector calibration is necessary. Such calibration measurements are performed as comparisons to the World Infrared Standard Group (WISG), operated at the World Radiation Center (WRC) in Davos. For its improved traceability to the SI, a new blackbody as reliable calibration source is proposed in the framework of the EU co-funded research project MetEOC3 – “Further metrology for Earth Observation and Climate”. One of the aims in this project is to reduce the uncertainty of hemispherical long-wave downward irradiance measurements from currently 5 W/m2 to less than 2 W/m2. As one of several uncertainty components contributing to these measurements, the new blackbody calibration source needs to feature an irradiance uncertainty of less than 0.5 W/m2. In combination with “Infrared Integrating Sphere” (IRIS) instruments, calibrated against the blackbody, irradiance responsivity traceable to the SI can be transferred to the WISG with the required uncertainty.
