24-29 June 2007 CEDAR WorkshopSanta Fe, New Mexico SuperDARN – PolarDARN It is appreciated that empirical models of this convection that generate statistical convection patterns fails to capture adequately the spatial and temporal aspects of the energy and momentum exchange. We need better convection descriptions especially for I-T model studies that are to be compared against I-T observations. IPY campaign models need SuperDARN! Energy and momentum “from and to” the Ionosphere-Thermosphere always has a major contribution from the convection electric field.

24-29 June 2007 CEDAR WorkshopSanta Fe, New Mexico First Three Months of the IPY Campaign International Polar Year (IPY) began on 1 March 2007 IPY is occurring during a “deep” solar minimum, or is it?

24-29 June 2007 CEDAR WorkshopSanta Fe, New Mexico Modelers Need the Convection Pattern at all Times During the 18 Months of the IPY-Campaign SuperDARN has them. How do we interface them to the various I-T models? Even during the quietest periods the SuperDARN patterns are useable. As activity increase Kp > 3. The cusp-polar cap convection patterns are dramatic and depart from standard empirical models.

24-29 June 2007 CEDAR WorkshopSanta Fe, New Mexico Our Problem Assume every 5 minutes SuperDARN generates a convection pattern. The IPY campaign began 1 March 2007 and will end towards the end of 2008! (400 days 24 hours 12) convection patterns. Magnetic latitude resolution = ? Magnetic local time resolution = ? Need the 2-D potential data sets. ? 1 CD every three months?
