TL;DR: In this paper, the authors consider the nature of snow at a fundamental, physical level; photochemical processes within snow and the caveats needed for comparison to atmospheric photochemistry; our current understanding of nitrogen, oxidant, halogen and organic photochemistry within snow; the current limitations faced by the field and implications for the future.

TL;DR: Satellite radar altimetry measurements indicate that the East Antarctic ice-sheet interior north of 81.6°S increased in mass by 45 ± 7 billion metric tons per year from 1992 to 2003, enough to slow sea-level rise by 0.12 ± 0.02 millimeters per year.

TL;DR: A review of physical processes and chemical reactivity in surface snow with relevance to polar regions is presented in this paper, focusing on impurities in distinct compartments of surface snow, such as snow crystals, grain boundaries, crystal surfaces, and liquid parts.

TL;DR: In this paper, the spatial and temporal variability of major runoff components in the mountainous Brugga basin (Black Forest, Germany) were examined during single events and over a period of 3 years.

TL;DR: In this paper, a comprehensive isotopic composition of atmospheric nitrate (i.e., the simultaneous measurement of all its stable isotope ratios: 15N/14N, 17O/16O and 18O /16O) has been determined for aerosol samples collected in the marine boundary layer (MBL) over the Atlantic Ocean from 65°S (Weddell Sea) to 79°N (Svalbard), along a ship-borne latitudinal transect.
