Causes of variability in light absorption by particles in snow at sites in Idaho and Utah.
The data presented are from samples of snow gathered approx. every few days at three sites in central Idaho from 27 January to 24 March 2014. In most cases samples were gathered at intervals throughout the snowpack depth. In a few cases we only sampled newly-fallen surface snow. Samples were also collected from a site to the ...
Formic acid mixing ratio (CIMS) and 3D wind data, plus SOSAA model runs -- Hyytiälä, Finland, Apr-Jun 2014
These are data of eddy covariance flux measurements of formic acid (HCOOH), performed by a chemical ionization mass spectrometer (CIMS) over a boreal forest canopy in Hyytiälä, Finland, in spring/summer 2014. Results from the 1-D chemical transport model runs using SOSAA (Simulate Organic vapours, Sulphuric Acid and Aerosols) ...
North American Monsoon GPS Transect Experiment 2013
Northwest Mexico experiences large variations in water vapor on seasonal time scales in association with the North American monsoon (NAM), as well as during the monsoon associated with upper tropospheric troughs, mesoscale convective systems, tropical easterly waves and tropical cyclones. Together these events provide more ...
The magnitude of the snow-sourced reactive nitrogen flux to the boundary layer in the Uintah Basin, Utah, USA
(Atmospheric Chemistry and Physics, 2016)
Reactive nitrogen (Nr=NO, NO2, HONO) and volatile organic carbon emissions from oil and gas extraction activities play a major role in wintertime ground-level ozone exceedance events of up to 140 ppb in the Uintah Basin in eastern Utah. Such events occur only when the ground is snow covered, due to the impacts of snow on the ...
Supporting output files for Wyant et al. (2018), The Sensitivity of Numerical Simulations of Cloud-Topped Boundary Layers to Cross-Grid Flow
This collection of large-eddy simulation output files can be used to generate the figures in the research paper Wyant et al. (2018), The Sensitivity of Numerical Simulations of Cloud-Topped Boundary Layers to Cross-Grid Flow, published in Journal of Advances in Modeling Earth Systems.
Productivity and Climate Responses to Forest loss in North American Ecoregions
Regional-scale tree die-off events driven by drought and warming and associated pests and pathogens have occurred recently on all forested continents and are projected to increase in frequency and extent with future warming. Within areas where tree mortality has occurred, ecological, hydrological and meteorological consequences ...

Parameterizations for narrowband and broadband albedo of pure snow, and snow containing mineral dust and black carbon
(Journal of Geophysical Research, 2015-04)
The reduction of snow spectral albedo by black carbon (BC) and mineral dust, both alone and in combination, is computed using radiative-transfer modeling. Broadband albedo is shown for mass fractions covering the full range from pure snow to pure BC and pure dust, and for snow grain radii from 5 μm to 2500 μm, to cover the ...
