Intercomparison of erythemal broadband calibrations performed by AEMET and INTA laboratories

Abstract

National Radiometric Laboratory of AEMET calibrates the AEMET's network of broadband UV radiometers following recommendations of the WMO for this type of calibrations, with a procedure that includes characterisation of each radiometer in the laboratory, utilisation of a radiative transfer model and absolute calibration through a spectral reference instrument using the sun as source.

Intercomparisons between several radiometric laboratories are organized periodically for ensuring consistency of whole process of calibration. This technical note describes the first intercomparison between the calibrations at INTA and AEMET laboratories for broadband UV radiometers organised in September 2009.
