A new parameterization of ice heterogeneous nucleation coupled to aerosol chemistry in WRF-Chem model version 3.5.1: evaluation through ISDAC measurements [PDF]
Geoscientific Model Development, 2020 In the Arctic, during polar night and early spring, ice clouds are separated into two leading types of ice clouds (TICs): (1) TIC1 clouds characterized by a large concentration of very small crystals and TIC2 clouds characterized by a low concentration ...

A glaciochemical study of the 120 m ice core from Mill Island, East Antarctica [PDF]
Climate of the Past, 2017 A 120 m ice core was drilled on Mill Island, East Antarctica (65°30′ S, 100°40′ E) during the 2009/2010 Australian Antarctic field season. Contiguous discrete 5 cm samples were measured for hydrogen peroxide, water stable isotopes, and trace ion ...

Sea-ice melt CO2–carbonate chemistry in the western Arctic Ocean: meltwater contributions to air–sea CO2 gas exchange, mixed-layer properties and rates of net community production under sea ice [PDF]
Biogeosciences, 2014 The carbon dioxide (CO2)-carbonate chemistry of sea-ice melt and co-located, contemporaneous seawater has rarely been studied in sea-ice-covered oceans. Here, we describe the CO2–carbonate chemistry of sea-ice melt (both above sea-ice as "melt ponds" and

Isotopic variations of meltwater from ice by isotopic exchange between liquid water and ice
Journal of Glaciology, 2019 Predicting the isotopic modification of ice by melting processes is important for improving the accuracy in paleoclimate reconstruction. To this end, we present results from cold room laboratory observations of changes in the isotopic ratio (D/H and 18O ...

Halogen activation via interactions with environmental ice and snow in the polar lower troposphere and other regions [PDF]
Atmospheric Chemistry and Physics, 2012 The role of ice in the formation of chemically active halogens in the environment requires a full understanding because of its role in atmospheric chemistry, including controlling the regional atmospheric oxidizing capacity in specific situations.

Modeling the processing of interstellar ices by energetic particles [PDF]
, 2013 Context. Interstellar ice is the main form of metal species in dark molecular clouds. Experiments and observations have shown that the ice is significantly processed after the freeze-out of molecules onto grains.

Photodissociation of water in crystalline ice: a molecular dynamics study [PDF]
, 2005 Ultraviolet irradiation of ice is of great interest for understanding the chemistry in both atmospheric and astrophysical environments. In interstellar space, photodissociation of H2O molecules can be a driving force behind the chemistry on icy dust ...
