The CanESM2 large ensembles are 50-member perturbed initial condition ensembles from 1950 to 2020, with all historical forcings (historical), solar and volcanic forcings only (historicalNat), anthropogenic aerosols only (historicalMisc, p4), and ozone only (historicalMisc, p6). The model,...

The purpose of Bird Conservation Regions strategies is to summarize the important issues and to recommend the actions required to conserve populations of birds in Canada. The Bird Conservation Regions (BCR) used as the basis for our planning units are based on the Commission for Environmental...

At all locations the TGM measurements were made using automatic Tekran ® 2537 mercury vapour analyzers (described in detail in Poissant, 1997). The air is typically sampled at flow rates between 1.0 and 1.5 L/min (depending on location) and is passed through a Teflon filter (47 mm diameter; 0.45...

The Non-Methane Hydrocarbons (NMHC) Measurements Study was a continuous measurement program carried out at the Centre for Atmospheric Research Experiments (CARE) at Egbert, ON. Approximately 30 C2 to C8 hydrocarbons (in gaseous form) were collected and analyzed every three hours by an automated,...

Ground level ozone measurements, sometimes referred to as in situ measurements are those measurements that occur close to the ground, i.e. within the boundary layer which is approximately 1 kilometre in height. Ongoing network measurements from the Canadian Air and Precipitation Monitoring...

Measurements of gaseous elemental mercury (GEM), gaseous oxidized mercury (GOM) and particulate bound mercury on PM2.5 (referred to as PBM) are currently collected by Environment and Climate Change Canada at a Wood Buffalo Environmental Association (WBEA) Air Monitoring Station (AMS)....
