IPY: Pan-Arctic Study - AON1 IPY: Pan-Arctic Studies of the Coupled Tropospheric, Stratospheric and Mesospheric Circulation. Richard L. Collins 1, David E. Atkinson 1, V. Lynn Harvey 2 1: University of Alaska Fairbanks 2: University of Colorado PFRR ALOMAR ESO SUARF

IPY: Pan-Arctic Study - AON2 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 - AON3 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 - AON4 Rayleigh Lidar Soundings

IPY: Pan-Arctic Study - AON5 The Arctic Vortex and Anti-Cyclone

IPY: Pan-Arctic Study - AON6 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 and

IPY: Pan-Arctic Study - AON7 Daily Briefing

IPY: Pan-Arctic Study - AON8 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 - AON9 Other Important Information This study is a component part of IPY-SPARC ( and IPY-IASOA ( 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.
