MAPP-EMPIR - Metrology for Aerosol Optical Properties (19ENV04 MAPP)
The overall aim of this project is to enable the SI-traceable measurement of column-integrated aerosol optical properties retrieved from the passive remote sensing of the atmosphere using solar and lunar radiation measurements. We will calibrate radiometers of the three largest aerosol monitoring networks at NMI laboratories and develop portable devices for the in-field calibration of network radiometers in order to validate and improve the current aerosol optical property retrievals using state-of-the-art inversion models. The goal is to standardise aerosol optical properties retrieval by shortening the calibration chain, reduce calibration downtime of network radiometers and establish their consistent dissemination including their uncertainty.
