In 2016 NETCARE scientists conducted two measurement campaigns at the Dr. Neil Trivett Global Atmosphere Watch Observatory (the “Alert Observatory”) on the northeastern tip of Ellesmere Island in the Canadian Arctic (latitude: 82.5163, longitude: -62.3085).

The first campaign happened in March and was focused on ice nucleating particles and aerosol particle composition. Further measurements were made in the summer (June- Sept) on aerosol particle size and number density, gas phase species, aerosol optical properties, aerosol particle composition, and soluble gases and ions in particulate matter.

Measurements of aerosol optical depth (AOD) using sunphotometers are being made in the oil sands region (at Fort McKay’s Oski-ôtin site, and Fort McMurray). AOD is a measure of the degree to which atmospheric aerosols absorb or scatter sunlight anywhere from the top of the atmosphere to the ground. These tiny solid or liquid particles can have natural or anthropogenic sources including dust, sea salt, smoke, or pollutants. Measurements of AOD made in the oil sands region can be compared with data collected at other Canadian locations from the AErosol RObotic CANadian (AEROCAN) network, such as Kelowna, BC; Lethbridge, AB; Bratt’s Lake and Waskesiu, SK; and Yellowknife, NT.

Ten NETCARE scientists were on board the Canadian Coast Guard Ship Amundsen, a research icebreaker, studying atmospheric and oceanic composition throughout the central Arctic in 2014. The cruise departed from Quebec City on July 8, entered Lancaster Sound on July 17, underwent a partial exchange of scientists at Resolute Bay, Nunavut on July 24, and then headed west through the Northwest Passage. All NETCARE scientists left the ship on August 14 in Kugluktuk, Northwest Territories. The research goal was to assess the impact of the ocean in promoting the formation of atmospheric aerosols.

Black carbon is a short-lived, small aerosol (or airborne) particle linked to both climate warming and adverse health effects. It is emitted from incomplete combustion of carbon-based fuels (i.e., fossil fuels, biofuels, wood) in the form of very fine particulate matter. Black carbon is not emitted on its own, but as a component of particulate matter less than or equal to 2.5 micrometres in diameter (PM2.5). As a member of the Arctic Council, Canada has committed to producing an annual inventory of black carbon emissions.

Air emissions from oil sands development can come from a number of sources including industrial smokestacks, tailings ponds, transportation, and dust from mining operations. Air quality monitoring under the Joint Canada-Alberta Implementation Plan for the Oil Sands is designed to determine the contribution of emissions from oil sands activities to local and regional air quality and atmospheric deposition both now and in the future. Ambient air quality data include:

  • Filter Pack (24-hour integrated concentrations of particle-bound SO2-4, NO-3, Cl-, NH+4, Ca2+, Mg2+, Na+, K+ and gaseous SO2 and HNO3 collected daily by the Canadian Air and Precipitation Monitoring Network)

  • Total Gaseous Mercury (hourly mixing ratios measured by the Canadian Air and Precipitation Monitoring Network and Prairie and Northern Region)

  • Atmospheric speciated mercury (Hg) (2-hour average concentrations of gaseous elemental Hg (GEM), reactive gaseous Hg (RGM), and Hg on PM2.5 (total particulate Hg - TPM)

  • Comprehensive set of measurements collected from an aircraft (various time resolutions) covering an area of 140,000 km2 over the oil sands region

  • Comprehensive set of measurements collected from the Fort McKay Oski-ôtin monitoring site

  • Ozone (hourly mixing ratios measured by the Canadian Air and Precipitation Monitoring Network)

  • Ozone Vertical Profiles (ozone mixing ratios as a function of height) measured by the Canadian Ozone Sonde Network

  • Aerosol Optical Depth (measure of the degree to which the presence of aerosols in the atmosphere prevents the transmission of light, from the ground to the top of the atmosphere) measured as part of the AErosol RObotic CANadian (AEROCAN) network

  • Satellite overpass data have a relatively high spatial resolution over the Oil Sands region to produce images and geo-referenced data of nitrogen dioxide (NO2) and sulphur dioxide (SO2) “vertical column density” (which correlates with surface concentration)

LIDAR (LIght Detection And Ranging) is a measurement technique capable of observing the complex vertical structure of the atmosphere. Specifically, information can be provided related to the existence and extent of aerosols and clouds with high spatial (4 m vertical) and temporal (1 min) resolution, making it well-suited for understanding atmospheric dynamics and transport processes. ECCC researchers designed, built and deployed autonomous ground-based aerosol LIDAR systems to three different locations in the oil sands region – AMS13 (November 2012 to September 2013), Oski-ôtin (October 2013 to present) and Mannix (July 2013 to March 2016). Details of the instrument by Strawbridge, 2013 can be found in Atmos.

Description

In August 2013, NETCARE scientists conducted a campaign on the west coast of Vancouver Island, British Columbia, Canada. The goal of this campaign was to characterize the nature of ice nuclei in a marine environment. Measurements were conducted on the ambient levels of both deposition and immersion ice nucleating particles. Data was also collected to measure the physical and chemical properties of the ambient particles.

SARS-CoV-2, the virus that causes COVID-19, spreads from an infected person to others through respiratory droplets and aerosols when an infected person breathes, coughs, sneezes, sings, shouts, or talks. The droplets vary in size, from large droplets that fall to the ground rapidly (within seconds or minutes) near the infected person, to smaller droplets, sometimes called aerosols, which linger in the air, especially in indoor spaces.
