The measurements with the Microtops also contribute to NASA's Maritime Aerosol Network (MAN), as part of the Aerosol Robotic Network (AERONET). In addition, the instrument measures precipitable water vapor (PWV). This specific MICROTOPS II model is equipped with four channels operating at wavelengths of 380, 440, 675, and 870 nm. The instruments were calibrated before and after the field campaigns according to the procedure described by Smirnov et al. (2009), JGR.
