1.1 Participation in the measurement campaign in 2007 - Greenland Flow Distortion

The purpose of GFDex is to investigate the influence of Greenland on flows at various spatial scales, e.g., barrier winds, tip jets, meso-cyclones and synoptic-scale cyclones.
For this purpose a U.K. aircraft (FAAM) will be stationed at Keflavík, Iceland for a 3-week period in February-March 2007. This is the first time ever that a dedicated measurement campaign aimed at understanding the influence of Greenland on air flow is conducted. It will seek to answer questions raised by modeling studies, as well as providing valuable data for future modeling investigations aimed at improving forecasts of high-impact weather downstream of Greenland.

The main funding of GFDex is from NERC in the U.K., and the principal investigator is Dr. Ian Renfrew of the University of East Anglia, while Dr. Kent Moore of the University of Toronto, Canada is a co-investigator. Another key investigator is Prof. Haraldur Ólafsson of the University of Iceland in Reykjavík. In addition, Jón Egill Kristjánsson has received funding from the EU infrastructure programme EUFAR (European Fleet for Airborne Research, http://www.eufar.net/) for 9 flight hours, which will complement the British and Canadian initiatives. Both Kristjánsson and a Ph.D. student from the University of Oslo (Ivan Føre) have funding from EUFAR to participate in the campaign, while Idar Barstad and Erik Kolstad will participate as observers. In this way, the GFDex will serve as a pilot experiment for the Norwegian-led IPY-Thorpex campaign in January-March 2008.
