dc.description.abstractThe filter band function of filter radiometers is frequently used in AOD retrieval to improve the accuracy of the Rayleigh and gaseous absorption contributions to the total optical depth. These contributions to the total optical thickness are overestimated when the band-pass filter curve used in the computation exceeds the lower limit of the detector response range (around 320 nm). It can be the case for some typical band-pass filters used in the ultraviolet region (e.g. 340 or 380 nm). This error can involve a strong impact on the aerosol optical depth accuracy, underestimating its value. Errors as large as 0.047 in the evaluation of ozone optical depth at 340 nm, and 0.009 in the Rayleigh optical depth were found, leading to final errors of 50–100% in the AOD for remote locations, like Polar regions or high mountains. To avoid this significant error, the detector spectral response must be taken into account in the computations. Further, it is recommended to discard the filter band-pass function when the transmittance falls below 1% of its maximum value at the central wavelength.es_ES
