Preparing Reagents: Time Dependence of HCl(v =1, J) Alignment Following Pulsed Infrared Excitation
TL;DR: In this paper, a linearly polarized infrared beam from an optical parametric oscillator was used to align reagents for studies of dynamical stereochemistry, and the alignment was monitored at subsequent times by (2+1) resonanceenhanced multiphoton ionization.
Journal ArticleDOI
Verification of snowpack radiation transfer models using actinometry
TL;DR: In this paper, the authors used the delta-Eddington method and the discrete ordinate method to estimate the photolysis rate coefficient of 2-nitrobenzaldehyde (NBA) in the tropospheric ultraviolet and visible snow model.
Journal ArticleDOI

TL;DR: A buoy based instrument platform (O-buoy) was designed, constructed, and field tested for year-round measurement of ozone, bromine monoxide, carbon dioxide, and meteorological variables over Arctic sea ice as mentioned in this paper.

Simulation of the specific surface area of snow using a one-dimensional physical snowpack model: implementation and evaluation for subarctic snow in Alaska
TL;DR: In this paper, two different types of empirical parameterizations of the specific surface area (SSA) of snow are im- plemented into the existing one-dimensional snow physics model CROCUS.
