Tuneable laser-based calibration of filter radiometers from surface-based aerosol monitoring networks in Europe

12.04.2024

Optical properties of atmospheric aerosols, such as aerosol optical depth (AOD), are determined from solar radiation measurements using filter radiometers, known in such measurement applications as sun photometers. Here we present calibration of filter radiometers from the European branches of aerosol monitoring networks AERONET, GAW-PFR, and SKYNET with respect to their spectral irradiance responsivities. The calibrations were carried out at PTB within the framework of the EMPIR project 19ENV04 MAPP “Metrology for aerosol optical properties” using the tunable laser-based setup, TUable Lasers In Photometry (TULIP). The realization of the spectral responsivity measurements of the filter radiometers at the TULIP setup, results, uncertainty contributions and implications are discussed in this conference paper.
