Comment:

Aerosol optical thickness (AOT) has been measured during POLARSTERN cruise ARK-XXVII/3 (IceArc) in 2012 in the Central Arctic. The AOT was measured with a hand-held sunphotometer Microtops. The file contains photometer signals for 5 wavelengths along with date, geolocation, air temperature and pressure, solar zenith angle and channel ratios. This raw data has been processed up to level 1.5 within Maritime Aerosol Network (see Source data set link above).
