Analysis of aerosol optical depth evaluation in polar regions and associated uncertainties

P. Ortiz de Galisteo, C. Toledano, V. Cachorro, E. Rodríguez, and A. de Frutos

Abstract. Some available processing algorithms used to calculate the aerosol optical depth from radiometric measurements were tested. The aim was to evaluate the associated uncertainties in polar regions due to the data processing, in order to adjust the methodology of the calculation and illustrate the importance of these error sources. The measurements were obtained during a sun photometer campaign in Ny-Ålesund within the framework of the POLAR-AOD project.
