Davos Instruments is comparing a PMO8 radiometer to the irradiance reference of the Laboratory for Atmospheric Science (LASP) and Space Physics at the University of Colorado in Boulder. LASP’s total solar irradiance radiometer facility (TRF) allows to compare the PMO8 to the NIST traceable reference radiometer NACR5 (White et al. 2022) in a indoor laboratory environment.
