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.
Amundsen 2016 Campaign
It's hard to believe that the NETCARE campaign on board the CCGS Amundsen has already been in operation for 2 weeks . We were sad that Joannie left us at Qikiqtarjuaq for the science crew rotation but were excited to welcome Marjo, Aude and Doug. There are now ten of us on board studying different aspects of how the ocean and atmosphere interact, including dimethyl sulphide concentrations in the water and the atmosphere, plankton taxonomy, ammonia sources and sinks, sea spray emissions, and ice and liquid
Today we successfully deployed the skimmer for the second time this leg. It collects surface microlayer and bulk water, which we will be analyzing for various biological, chemical and physical properties. Details from some of these measurements will be described by others later.
The first part of this leg has been in Davis Strait but we are moving into Baffin Bay followed by Nares Strait and there will be many opportunities for sampling in the ocean.

HQP Training at UDAL
In spring 2016 (from May 15 to 20), I had the opportunity to visit Rachel Chang and also meet with Richard Leaitch at Dalhousie University in Halifax to discuss and learn more about NETCARE’s aircraft observations related to cloud micro-physical processes and aerosols. It was an exciting journey traveling all the way from Canada’s west coast (Victoria, BC) to the east coast (Halifax, NS).
The meeting was motivated by the proposed simulations of the observed cloud micro-physical properties using a single column model. Most of the discussions were related to comparing single column model simulations, and GCM simulations, with aircraft measurements. We were particularly lucky to have Richard for discussions on aircraft measurements that clarified many questions that we had regarding observations and single column model simulations. Special thanks to Rachel Chang for hosting this event and to Richard Leaitch for giving us time and providing his expert opinions and thoughts both on observations and model simulations.

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:
