POLAR6 Campaign 2015

This campaign took place in April 2015, with the focus upon the characterization of ice clouds and pollutant levels, including black carbon, across the Arctic.  The campaign was again a collaboration between NETCARE scientists and AWI.   Along with the POLAR 6, the POLAR 5 make the trans-Arctic passage with its intent to characterize sea ice levels.  The campaign started in Longyearben, Spitzbergen and was to have continued in Station Nord, Greenland but bad weather at the start required us to skip science activities in Station Nord and to pass to Alert and Eureka, Nunavut and then onto Inuvik, NWT.

The instrumentation (list below) was similar to that flow in the summer 2014 but with specific changes to better characterize the optical properties of the particles and the character of the ice clouds.   Close to 10 science flights were performed, with some measurements also performed on the ferry flights between stations. During the campaign our scientists submitted updates that can be found in the NETCARE activities blog.
