Project Description:
This Palmer Station research project is a collaboration with Australian scientists who have Fabry-Perot interferometer (FPI) instruments at the Australian Mawson and Davis Stations to jointly analyze the neutral wind and temperature data to address the following issues: (1) Thermospheric neutral wind effect on the Weddell Sea Anomaly; (2) Lower thermosphere wind effect on shuttle plume drift; (3) Non-migrating tides in the mesosphere and lower thermosphere; and (4) Geomagnetic effect on the thermospheric wind.

Field Season Overview:
This project will install and operate a new Fabry-Perot interferometer (FPI) mesospheric and thermospheric neutral wind and temperature observation site at Palmer Station. The equipment was installed in 2009-10 and two field team members will service the instrument at Palmer Station each year. The Palmer Station site is part of a larger project that includes FPI instruments at Mawson and Davis Stations operated by the Australian Antarctic program. American and Australian researchers jointly analyze the neutral wind and temperature data seeking to understand more about (1) Thermospheric neutral wind effect on the Weddell Sea Anotmaly; (2) Lower thermosphere wind effect on shuttle plume drift; (3) Non-migrating tides in the mesosphere and lower thermosphere; and (4) Geomagnetic effect on the thermospheric wind.
