The Alliance Icing Research Study (AIRS) is a collaborative effort involving several Canadian and U.S. research agencies and Universities. AIRS is a project endorsed by the Aircraft Icing Research Alliance (AIRA), which consists of government organizations within North America interested in aircraft icing. It is also being supported by the World Meteorological Organization (WMO) World Weather Research Program (WWRP) project on Aircraft In-Flight Icing.
The First Alliance Icing Research Study (AIRS I) occurred during 1999-Nov-19 to 2000-Feb-18 using 3 aircraft stationed out of Ottawa and remote sensing hardware located at both Ottawa and Mirabel to investigate the remote sensing of aircraft icing and other aircraft icing issues. Some publications resulting from this work can be found on this Web site.
AIRS 1.5 was a small project undertaken in the same area (December 2002 to February 2003). The Meteorological Service of Canada, and the National Research Council of Canada used this period to prepare for AIRS II.
The Second Alliance Icing Research Study (AIRS II), which built on the results of AIRS I, was conducted from 2003-Nov-03 to 2004-Feb-20.
