“…At the same time, a significant amount of black carbon was observed in the atmosphere above the coast near Maitri station in East Antarctica [68]. Based on this, the authors [69] suggested that the eruption of Mount Chaitén was a source of black carbon that moved from the volcanic front to the border of East Antarctica along with the near-polar current. In general, the primary sources of black carbon in the Southern Hemisphere are biomass burning in Australia, South America and Africa [70].…”

Black carbon is considered a product of the incomplete combustion of fossil fuels and materials that originated from volcanic eruptions or were emitted during wildfires. It is a strong light-absorbing component that has many atmospheric and surface effects in terrestrial and glacial ecosystems. Normally, black carbon is presented as a solid particle, consisting mainly of pure carbon, which absorbs solar radiation at all wavelengths. Some black carbon particles are amended by a mineral compound, though black carbon substances are normally dark or greyish dark. Black carbon is the most active part of suspended particles in the atmosphere and on glacial surfaces, absorbing solar radiation, the main component of ash, which consists of carbon particles with impurities in the form of mineral particles and also contains carbon of biogenic origin. In this paper, we have analyzed the literature on black carbon and its effect on deglaciation processes in the Earth’s polar and mountainous regions. The physical, chemical, and microbiological composition of black carbon accumulations were studied using the examples of the Arctic, the Antarctic, and the Central Caucasus. Potential sources and conditions of the transportation of black carbon into the polar zone and their effect on ice and snow have also been discussed.

The Tonga volcano erupted with a mass of energy released into the plate and atmosphere, causing variations in the relevant geophysical parameters. Thus, we creatively apply the observations from space‐borne and ground‐based sensors to reveal the characterizations of up to four items (tropospheric response, sea surface temperature, surface deformation, and ionospheric reaction). The results of precipitable water vapor (PWV) from space‐borne and ground‐based data show that tropospheric response has a trend of rising first, after the volcano event dropping sharply, then recovering to the normal level. The reaction of sea surface temperature (SST) shows a slight rise of 0.5‐1 °C caused by the incident. Examining ground‐based GNSS station coordinates illustrates that the volcano eruption causes surface deformations up to 46 cm in the northeast direction. Eventually, for the ionospheric reaction, a similar characterization of the tropospheric response is found in the total electron content (TEC) variation. These are the first comprehensive analyses showing the impacts of the Tonga volcano on multiple types of parameters using both space‐borne and ground‐based data from low to high frequency.

“…During its change, water vapor absorbs and releases large amounts of latent heat, directly affecting ground and air temperatures and thus influencing the formation and evolution of weather systems. Numerous studies have shown anomalous changes in water vapor both before and after geological hazards [15][16][17]; for example, there may be a sudden increase in columnar water vapor in the atmosphere before an earthquake, and this is attributed to increased evaporation due to increased surface heat flux. Water vapor may decrease after an earthquake, while over the ocean, water vapor is found to increase after an earthquake [18].…”

Research concerning the response characteristics of lower atmosphere to volcanic eruption is a key and hot topic in the field of volcanic environment research. Against the background of a submarine volcano in the South Pacific island country of Hunga Tonga–Hunga Ha’apai (HTHH) on 15 January 2022, this paper explores the response characteristics of this volcanic eruption on environmental factors in the lower atmosphere region using a priori data such as ERA5 reanalysis data, water vapor data from GNSS inversion and surface temperature data from Landsat inversion for the Tonga Islands region. Among them, (1) The amount of precipitable water (PWV) in Tonga was abnormally high on 15 January. (2) The water vapor flux was mainly in the lower space below 850 hPa. (3) The average surface temperature in December 2021 was higher. In February 2022, the average surface temperature was lower. (4) There was a low-pressure center near 30° S on the south side of Tonga volcano on 14 January, and a new low-pressure center was formed on the east side of Tonga volcano after the eruption of Tonga volcano on 15 January. Furthermore, the precipitation area of Tonga increased in January and decreased in February 2022. The PWV values, water vapor fluxes, temperature and circulation response characteristics, and precipitation characteristics show that the volcanic eruption affected part of the atmospheric and oceanic circulation, and water vapor was transported to the low-pressure center along the direction of atmospheric circulation. With the continuous water vapor transport, precipitation formed in Tonga, and the intensity and area of precipitation in Tonga increased significantly in January. Thus, the volcanic eruption could have significantly triggered the response between the low-pressure center, PWV, precipitation and surface temperature in the lower atmosphere, which influenced the environmental characteristics of this eruption.
