The JOULE sounding rocket experiment was carried out at the Poker Flat Research Range in Alaska on March 27, 2003. Two instrumented rockets and one chemical tracer rocket were lauched around 12:00UT, which followed many hours of geomagnetically active conditions. They measured the in-situ small-scale electric field, ion velocity and electric density in the upper mesosphere and low thermosphere. From the released trimethyl aluminum (TMA) trails, neutral wind profiles were provided. Since the Global Ionosphere Thermosphere Model (GITM) has a flexible grid structure, sub-degree resolution around the JOULE rocket position can be applied and relatively reasonable results in such a small-scale can be achived. Not only will the simulation results be compared with JOULE observations, but also the comparsion between simulations using different high-latitude drivers will be conducted. It will be shown that using AMIE results produces more accurate neutral wind patterns than empirical models, although the auroral precipitation pattern may be too wide in AMIE, producing too much E- region electron density within GITM. In order to show the significance of spatial variability, GITM will also be run with different resolutions. This study will help us validate the GITM model and understand the significance of small-scale structure to the Joule heating.
