“…The technique is applicable for pure snow cases common in Antarctica, where the atmospheric aerosol load is low [17,38]. The retrieval is performed outside absorption bands of water vapor, oxygen and carbon dioxide.…”

We proposed a simple algorithm to retrieve the total ozone column and snow properties (spectral albedo and effective light absorption path) using the high spatial resolution single–view MSI/S-2 measurements over Antarctica. In addition, the algorithm allows the retrieval of the snow grain size on a scale of 10–20 m. This algorithm should be useful for the understanding of intra-pixel total ozone and snow albedo variability in complement to satellite observations performed on a much coarser spatial resolution scale (0.3–1 km and even larger spatial scales).

“…(2) is higher as compared to the case of short-wave infrared wavelengths (Kokhanovsky et al, 2019). Also the influence of all atmospheric gases on the value of transmittance g T (except ozone) can be neglected in this spectral interval (Kokhanovsky et al, 2020b). This is especially valid in central Antarctica, where the atmosphere is thin and air is dry.…”

In this article, we describe multiannual variations of the atmospheric aerosol optical depth values in the widely understood area of the Baltic Sea. We present the trends in the changes and depict unusual aerosol situations. As a result of analyses, we focus on 2019, since unusually high values of aerosol optical depth were recorded in several stations around the Baltic. We match the high aerosol levels with an unusually high number of wildfires across Europe in spring and summer, which emitted large quantities of aerosols into the atmosphere that were distributed over vast European areas in part by the wind. We then connect this case with the climate change consequences. Since aerosols influence the radiative budget of the planet by directly affecting the atmospheric radiation budget, it is obvious that human well-being is in danger due to wildfires, as well as from the atmospheric perspective. Climate change will lead to more frequent fires; thus, humans need to develop solutions to decrease the risk of fire outbreaks.
