Meteoroids of sub-milligram sizes burn up high in the Earth's atmosphere and cause streaks of plasma trails detectable by meteor radars. The altitude at which these trails, or meteors…
Global chemistry–climate models (CCMs) play an important role in assessing the climate and air pollution implications of aerosols and chemically reactive gases.
Antarctic krill (Euphausia superba Dana) is a key species of the Southern Ocean ecosystem, immensely abundant and targeted by the krill fishery. For their sustainable management, krill distribution and biomass estimates are required, typically achieved through acoustic-trawl surveys.
Levoglucosan (LEV) and two of its isomers, mannosan (MAN) and galactosan (GAL), are commonly used as biomass burning tracers, however 1,6-anhydro-?-D-glucofuranose (AGF), another isomer derived from biomass burning, is rarely identified or quantified in existing literature.

Understanding the causes of past atmospheric methane (CH4) variability is important for characterizing the relationship between CH4, global climate and terrestrial biogeochemical cycling.
During the summer of 2021, we conducted a comprehensive study on zooplankton communities along East Antarctica (55°E to 80°E) as part of the Trends in Euphausiids off Mawson, Predators, and Oceanography (TEMPO) survey program.
Nitrous oxide (N2O) is a long-lived potent greenhouse gas and stratospheric ozone-depleting substance that has been accumulating in the atmosphere since the preindustrial period. The mole fraction of atmospheric N2O has increased by nearly 25?% from 270?ppb (parts per billion) in 1750 to 336?
Carbon monoxide (CO) is a naturally occurring atmospheric trace gas, a regulated pollutant, and one of the main components determining the oxidative capacity of the atmosphere. Evaluating climate…
Insoluble nanoparticles in the form of aerosols have significant effects on climate and biogeochemical cycles. Records of these aerosols are essential for understanding paleoclimate forcing and future climate change.
Insoluble nanoparticles, in the form of aerosols, have significant affects on climate and biogeochemical cycles. Records of these aerosols are essential for understanding paleoclimate forcing and future climate change. While a large body of research exists with respect to mineral dust particles…
Atmospheric electric field … measurements from the Concordia station on the Antarctic Plateau are … compared with those from Vostok (560 km away) for the period of overlap … (2009–11) and to Carnegie (1915–29) and extended Vostok (2006–11) measurements.
Stratosphere-to-troposphere transport (STT) provides an important … natural source of ozone to the upper troposphere, but the characteristics of … STT events in the Southern Hemisphere extratropics and their contribution to … the regional tropospheric ozone budget remain poorly constrained. Here…
Reference IUGG-2058, Symposium M03 Weather and the Global Atmospheric Electric Circuit. Atmospheric electric field measurements from Concordia station on the Antarctic Plateau are compared with those from Vostok (560 km away) for the period of overlap (2009-2011) and to earlier Vostok (2006-2009)…
Southern Hemisphere climate reconstructions are limited by quantity and spatial coverage of well resolved paleoclimaterecords from the last 2000 years. This was the motivation to drill an ice core at a new site in East Antarctica…
