For outsiders the abbreviation PAMARCMIP is quite inscrutable and stands for 'Polar Airborne Measurements and Arctic Regional Climate Model Simulation Project'. Aim of the project is to get a better understanding of physical processes in the inner Arctic which is crucial for the assessment of the actual changes in the polar region. One example is to reduce uncertainties in regional and global model simulations which are important for future weather and climate prediction. Further important work during the flights with Polar 5 will be extended measurement of sea ice thickness as well as to provide unique data of aerosol, trace gases distributions, meteorological and atmospheric conditions. The flights are planned to start from Barrow, Alaska via Inuvik, Sachs Harbour, Resolute Bay, Eureka, Alert and Station North to end in Longyearbyen, Spitsbergen. The details you can look up on the graphic beside.Particularly the thickness of the sea ice will be of high interest during the expedition, with good cause. Over the last 30 years, the extent of summer sea ice has declined at a rate of 11.2% per decade. Sea ice extent plummeted to a record minimum in 2007. As the sea ice thickness and its extension, respectively minimization, are linked to each other, the data which are expected from the measurements hopefully improve the modeling and forecasts.Warning!
