  1. IPY: Pan-Arctic Studies of the Coupled Tropospheric, Stratospheric and Mesospheric Circulation. Richard L. Collins1, David E. Atkinson1, V. Lynn Harvey2 1: University of Alaska Fairbanks 2: University of Colorado PFRR ALOMAR ESO SUARF IPY: Pan-Arctic Study - AON

  2. Scientific Goals • To conduct an aeronomy study of the Arctic atmosphere that uses observations, modeling and theoretical interpretation to document 3-D structure and evolution of the Arctic vortex and anticyclones with emphasis on vortex-vortex interactions and stratospheric warming/mesospheric cooling events during IPY. • To determine our ability to forecast weather events in the troposphere based on observations and analyses of the mesosphere and stratosphere. • To study the coupling between anomalous stratospheric weather and tropospheric modes of variability during IPY. IPY: Pan-Arctic Study - AON

  3. Site Locations • Arctic Lidar Observatory for Middle Atmosphere Research, Andoya, Norway (69° N, 16° E). • Eureka Stratospheric Observatory, Eureka, Nunavut, Canada (80°N, 86°W). • Poker Flat Research Range, Chatanika, Alaska, USA (65° N, 147° W). • Sondrestrom Upper Atmospheric Research Facility, Kangerlussuaq, Greenland (67° N, 51° W). IPY: Pan-Arctic Study - AON

  4. Rayleigh Lidar Soundings IPY: Pan-Arctic Study - AON

  5. The Arctic Vortex and Anti-Cyclone IPY: Pan-Arctic Study - AON

  6. Data and Measurements • High-resolution temperature measurements (~ 500 m, 10’s of minutes) of the stratosphere and mesosphere (~40-80 km). • Meteorological analyses from the U.K. Meteorological Office (MetO), consisting of daily 3-D fields of temperature, geopotential height, and horizontal winds. • Temperature, geopotential height, carbon monoxide (CO), and water vapor data from the EOS Microwave Limb Sounder (MLS) instrument (Aura), the Atmospheric Chemistry Experiment (ACE) instrument (SCISAT-1) the Sounding of the Atmosphere using Broadband Emission Radiometry (SABER) (TIMED). • Focused on wintertime and springtime observations in 2007-2008 and 2008-2009. IPY: Pan-Arctic Study - AON

  7. Daily Briefing IPY: Pan-Arctic Study - AON

  8. Data Management • Data will be archived with a web-based portal maintained by University of Alaska. • University of Alaska and Colorado will create virtual observatory. • Host institutions will also make data available to community data bases (e.g. CEDAR). • Interested in investigating role of integrated AON virtual observatory and data base. IPY: Pan-Arctic Study - AON

  9. Other Important Information • This study is a component part of IPY-SPARC (http://www.atmosp.physics.utoronto.ca/C-SPARC/) and IPY-IASOA (http://www.iasoa.org/). • Observational data set will provide data for WAACM studies. • Fairbanks NWS office will consult on forecasting case studies. WRF model is currently being implemented at Arctic Region Super-Computer Center (ARSC). • Six-hour synoptic meteorological analyses are available with model output for tropospheric analyses. • Partners- • John Dragomir, NWS Fairbanks • Craig Heinselman , SRI International • Franz Josef Lubken, Institute of Atmospheric Physics • Kohei Mizutani, National Institute of information and Communications Technology • Robert J. Sica, University of Western Ontario • Contact: Richard Collins - rlc@gi.alaska.edu IPY: Pan-Arctic Study - AON
