https://www.pangaea.de/ information publisher tableDigital We operate a 7-wavelength aethalometer (Model AE33, Magee Scientific) since 2019 in the Aerosol and Trace Gas Observatory at Neumayer III Station in Antarctica. The aethalometer model AE33 collects aerosol particles continuously by drawing the aerosol-laden air stream through a spot on the filter tape. It analyzes the aerosol by measuring the transmission of light through one portion of the filter tape containing the sample, versus the transmission through an unloaded portion of the filter tape acting as a reference area. This analysis is done at seven optical wavelengths spanning the range from the near-infrared to the near-ultraviolet. The aethalometer calculates the instantaneous concentration of optically-absorbing aerosols from the rate of change of the attenuation of light transmitted through the particle-laden filter. The intake of the aerosol inlet can be found on top of the observatory at approx. 5-7 m above ground. completed Jurányi, Zsófia

Therefore even among the one-hour averages negative values are present.
