Welcome to the NETCARE Website
NETCARE (Network on Climate and Aerosols: Addressing Key Uncertainties in Remote Canadian Environments) is a network comprised of researchers from ten Canadian universities (Toronto, UBC, UQAM, Waterloo, UQAR, Laval, Dalhousie, Calgary, Sherbrooke, Victoria) and five partner institutions (Environment Canada, Fisheries and Oceans Canada, Alfred Wegener Institute, Max Planck Institute, Johannes Gutenberg University). NETCARE is one of seven networks funded by the new Climate Change and Atmospheric Research (CCAR) program at NSERC.
NETCARE 2016 Workshop - November 14th & 15th
The 2016 NETCARE Workshop will take place on Monday November 14th and Tuesday November 15th. Over 50 members of the network will participate in this two day event, with more than 15 talks and two poster sessions from NETCARE investigators, collaborators, and highly qualified personnel. Exciting new science presentations and focused discussion sessions will guide the network into it's final project year. The program for the workshop is available for download below.
Amundsen Campaign - Microlayer skimmer
The microlayer skimmer proved to be incredibly valuable during the 2016 NETCARE field campaign on board the CCGS Amundsen. The skimmer was designed to collect large volumes of the sea surface microlayer in a time efficient manner compared to manual hand sampling methods. We prepared for using the skimmer in the field way back in 2015 at the IOS in Victoria, where we spent a week to familiarize ourselves with the equipment. Despite some initial challenges with the skimmer’s deployment during the campaign, the operation of the skimmer quickly became a routine and effective procedure.
Each time the skimmer was deployed, we would leave the Amundsen in a zodiac and tow the skimmer to a suitable sampling location. Working in the zodiac was a lot of fun and an excellent opportunity for us collect samples in the field. Deployments ranged between choppy conditions in the open Arctic ocean to calm waters amid large icebergs. In the end, we collected concurrent microlayer and subsurface water samples for nearly a dozen sampling locations to be analyzed for dimethyl sulphide, surfactants, ammonia, ice nucleating particles, and hygroscopicity.
I would like to give a special thanks to the Coast Guard crew for helping Vickie and I with each deployment and making everything run smoothly. Without their support, patience and expertise, we would not have been able to make the skimmer deployments a success.

Update on the CCAR Network Enhancement Initiative (NEI)
In the spring of 2016, NSERC announced the availability of additional funds for CCAR Network Enhancement Initiatives (NEIs) that could be applied for via a short proposal. After consulting with all NETCARE Co-Investigators, a proposal was submitted and successfully funded to allow the following activities to occur:
1. NETCARE workshop: "Impacts of Arctic DMS Emissions on Future Climate". A targeted workshop on this topic will be held in January 2017 at the Institute for Ocean Sciences, Department of Fisheries and Oceans Canada, in Sidney BC. This small workshop will largely involve NETCARE personnel, and is being organized by Maurice Levasseur, Knut von Salzen and Nadja Steiner. The attraction of this small format meeting is that it will provide more time for in-depth discussion not possible during our much larger annual two-day NETCARE workshop.
2. Enhanced data archiving activities. One of the key products from the network is the detailed and largely unique data arising from 7 field campaigns, conducted from 2013 to 2016. Dr. Sarah Hanna (UBC) will lead these archiving issues with help from Dr. Felicia Kolonjari (ECCC). The data will ultimately be available via a public website hosted at Environment and Climate Change Canada.
3. Capstone conference on "Arctic Aerosol Research: Status and Research Needs". This meeting will be held in Toronto during the fall of 2017. Ideally it will be coordinated with a meeting of PACES (Air Pollution in the Arctic: Climate, Environment and Societies), an IGAC-sponsored activity. Leading scientists in Arctic aerosol research will join the NETCARE and PACES teams for this meeting, to discuss the state of science in the field. As well, we will have a final one-day NETCARE-only meeting, to wrap up the project.
With these new activities proceeding alongside our research plans, this will be a busy year as the NETCARE project moves towards completion.
NETCARE Research Configuration
NETCARE has been configured around four research activities that address key uncertainties in the field. The first three are focused on specific
aerosol-climate connections – Carbonaceous Aerosol (Activity 1), Ice Cloud Formation and Impacts (Activity 2), Ocean-Atmosphere Interactions (Activity 3) – that remain poorly characterized.
These will be addressed through a variety of observational approaches. The fourth - Implications of Measurements on Simulations of Atmospheric Processes and Climate (Activity 4) –
integrates the results from Activities 1-3, approaching the subject from a comprehensive modeling perspective so as to provide a broad assessment of aerosol climate effects. The figure
below illustrates the vision inherent to the network:
