Heterogeneous processes: Laboratory, field, and modeling studies [PDF]

open access: yes
The efficiencies of chemical families such as ClO(x) and NO(x) for altering the total abundance and distribution of stratospheric ozone are controlled by a partitioning between reactive (active) and nonreactive (reservoir) compounds within each family ...

Species richness, community composition, and species distribution patterns in Aleutian plants [PDF]

open access: yes, 2016
Thesis (M.S.) University of Alaska Fairbanks, 2016We conducted an analysis of vascular plant distributional patterns in the Aleutian Islands to identify and quantify the impact of potential Aleutian Island distance dispersal barriers and ecological ...

Volcanic deformation and degassing:the role of volatile exsolution and magma compressibility [PDF]

open access: yes, 2023
Integrating multi-parameter observations of volcanic processes is crucial for volcano monitoring. Qualitative models demonstrate that combining observations of volcanic deformation, gas emissions, and other parameters enhances the detection of volcanic ...

Comparison of the impact of volcanic eruptions and aircraft emissions on the aerosol mass loading and sulfur budget in the stratosphere [PDF]

open access: yes
Data obtained by the Stratospheric Aerosol and Gas Experiment (SAGE) 1 and 2 were used to study the temporal variation of aerosol optical properties and to assess the mass loading of stratospheric aerosols from the eruption of volcanos Ruiz and Kelut. It

Volcanic activity parameters and volcanism-climate relationships within the recent centuries [PDF]

open access: yes, 2011
The ejecta ofvolcanism, including gas-to-particle conversions, form atmospheric aerosol layers which influence the radiation processes and in consequence the climate. Thereby, the major explosive eruptions are of predominant interest.

Atmospheric Backscatter Model Development for CO Sub 2 Wavelengths [PDF]

open access: yes
The results of investigations into the problems of modeling atmospheric backscatter from aerosols, in the lowest 20 km of the atmosphere, at CO2 wavelengths are presented, along with a summary of the relevant aerosol characteristics and their variability,

Condensation nuclei measurement in the stratosphere for the NASA ACE program [PDF]

open access: yes
A condensation nucleus counter which operated at stratospheric pressures was developed, designed, and constructed. It was calibrated in the laboratory. Its response as a function of particle size and concentration was reported.

Glaciochemical records from the Saint Elias Mountains, Yukon, Canada [PDF]

open access: yes, 2005
While many paleoclimate records have been recovered from the North Atlantic sector of the Arctic, there is a gap in our understanding of climactic and environmental change in the North Pacific. Glaciochemical records from the St. Elias Mountains spanning
