چکیده
The manuscript describes a method to obtain spectral aerosol optical thicknesses from measurements with a spectroradiometer in the UV-visible range. The direct solar light is inferred from the difference between total radiation and diffuse radiation. The latter is obtained by the use of a sun blocking disc. An error budget is presented. The results are validated against the measurements with a co-located sunphotometer from the aeronet/photons network. The comparisons are presented with a lot of figures but the authors leave the interpretation to a large part to the reader. Some figures could

متن کاملValidation of UV-visible aerosol optical thickness retrieved from spectroradiometer measurements
Global and diffuse UV-visible solar irradiances are routinely measured since 2003 with a spectroradiometer operated by the Laboratoire d’Optique Atmosphérique (LOA) located in Villeneuve d’Ascq, France. The analysis of the direct irradiance derived by cloudless conditions enables retrieving the aerosol optical thickness (AOT) spectrum in the 330–450 nm range. The site hosts also sunphotometers ...

We would like to thank the reviewer for the useful comments and suggestions. Most of them have been taken into account. A change in the de-seasonalisation method and the calculation of trends lead to slight changes in the retrieved AOD trends. In addition the use of cloud flagging methodology to derive clear sky scans also for the Brewer MKII direct sun scans eliminated a (small) number of poin...

Comparisons of Cloud Microphysical Properties Retrieved from Different Algorithms during Aerosol Transport Events
Multi-spectral data from the MODerate resolution Imaging Spectroradiometer (MODIS) onboard the Terra spacecraft are used to derive cloud optical thickness and effective particle radius using the algorithm of Nakajima and Nakajima (1995). Microphysical cloud properties are retrieved during strong aerosol events from biomass burning to better understand the actual effects of cloud-aerosol interac...
