Abstract. Motivated by the need to predict how Arctic atmosphere will change in a warming world, this article summarizes recent advances made research consortium NETCARE (Network on Climate and Aerosols: Addressing Key Uncertainties Remote Canadian Environments) that contribute our fundamental understanding of aerosol particles as they relate climate forcing. The overall goal has been use an interdisciplinary approach encompassing extensive field observations range chemical transport, earth...

Abstract. Low clouds persist in the summer Arctic with important consequences for radiation budget. In this study, we simulate linear relationship between liquid water content (LWC) and cloud droplet number concentration (CDNC) observed during an aircraft campaign based out of Resolute Bay, Canada, conducted as part Network on Climate Aerosols: Addressing Key Uncertainties Remote Canadian Environments study July 2014. Using a single-column model, find that autoconversion can explain LWC...
Pulp and paper mills are known large emitters of air pollution creating potential environmental challenges human health impacts. This study assesses associated impacts from connected pulp facilities which operate in Edmundston, New Brunswick, Canada, Madawaska, Maine, United States (US). Despite operating within two regulatory jurisdictions on both sides the international border (in Canada US), have exceeded their approvals to national quality regulations multiple times between 2010 2017....

Particle Measurements at Alert, NunavutThe experimental methods for the particle microphysical and filter-based chemical measurements in Fig. 7 are discussed by Leaitch et al. (2013Leaitch ( , 2018)).Monthly-averaged values of N>50 (number concentration > 50 nm diameter), N>100, N15-N30 size interval 15 to 30 nm), N30-N50, N50-N100 inclusive period 2012-2014 shown 7a.One estimate effect growth newly-formed particles on concentrations range 15-100 is demonstrated using 2. Baseline estimated...
The radial and axial dependence of the mass density distributions in both laminar turbulent wakes 1.0 2.7 in. diameter spheres flown at Mach 13.5 nitrogen atmospheres have been determined using electron beam fluorescence probe technique. distribution temperature wake has also inferred by invoking assumption that is isobaric. Both may be characterized behavior 2 parameters: amplitude or on center line corresponding profile width. Experimental data are presented for these parameters.
150,000 extensive air showers of high electron density have been recorded at an altitude 2283 meters. Analysis the data in solar time for a wide range densities shows no evidence large semidiurnal variations previously reported by other groups. A possible explanation this difference may lie different methods selecting showers.
