1 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.

2 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?

3 24-29 June 2007 CEDAR WorkshopSanta Fe, New Mexico AMISR at Poker Flat (PFISR)

4 24-29 June 2007 CEDAR WorkshopSanta Fe, New Mexico TDIM Simulation for Poker Flat

5 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.

6 24-29 June 2007 CEDAR WorkshopSanta Fe, New Mexico Example of SuperDARN Convection for “Quiet” Geomagnetic Activity

7 24-29 June 2007 CEDAR WorkshopSanta Fe, New Mexico Example of SuperDARN “Disturbed” Geomagnetic Activity

8 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?
