AB: On the night of June 30, 2003, four rockets were launched from Wallops Island, VA. The first three rockets each carried a chemical tracer experiment, and were launched with a separation of approximately two and a half and one hours, respectively. Each chemical tracer release provided upleg and downleg horizontal neutral wind profiles. This paper focuses on the shears in the wind profiles and the changes in the neutral winds over time. We also discuss the correspondence of the variations in the wind profiles to the ionosphere conditions obtained from the on-site ionosonde which showed persistent sporadic E layers throughout the observation period. Further, we compare the horizontal neutral wind measurements to previous wind observations above Wallops Island under similar conditions.
