About
Peter Sperfeld is a leading figure in radiometric metrology and atmospheric remote sensing, whose work bridges the gap between laboratory precision and field applications. His primary research focuses on establishing SI-traceable calibration standards for solar and atmospheric measurements, ensuring that data from ground-based observatories and spaceborne sensors are globally comparable. A major contribution is his development of robust calibration protocols for transfer standards like RASTA, used by the German Aerospace Center (DLR). In a highly cited 2013 paper (17 citations), he demonstrated a dual-procedure calibration technique at PTB that provides redundancy and reliability for spectral radiance measurements. More recently, his 2023 work (12 citations) advanced the field by using three spectroradiometer systems to measure spectral aerosol optical depth from direct solar irradiance at the Izaña Atmospheric Observatory, achieving unprecedented SI traceability. This campaign highlighted his ability to translate laboratory metrology into real-world atmospheric monitoring. Sperfeld’s impact is evident in the adoption of his methods by national metrology institutes and atmospheric networks, making him a key contributor to the accuracy of climate and air quality data.
