Aerosol optical thickness - DOORS 1 cruise, May 2023

The datasest aerosol optical depth measurements collected during R/V Mare Nigrum cruise carried out in Romanian Black Sea waters, 1-20 May, 2023 in the framework H2020 DOORS Project. Thirty-ehight (38) measurement series spanning 14 days were acquired during the cruise. Aerosol optical depth measurements were performed at stations and between stations during clear sky conditions. Measurements were carried out with hand held Microtops II sun-photometers equipped with five spectral channels within the spectral range 440–936nm.
