Winds and temperatures in the upper atmosphere above and between Mawson and Davis

Data products of analysed data show wind speeds and directions and temperatures in the upper atmosphere above, around and between Mawson and Davis Stations in Antarctica. Data are collected from approximately the heights at which green and red aurora occur.Raw data are recorded photographically with very sensitive CCD cameras as sets of interference fringes formed in Fabry-Perot Interferometers by light from airglow or aurora. Light from other sources like the moon and stars are filtered out. From very small changes in the interference patterns Doppler shifts in the wavelength of the light are inferred. Wind speeds and directions, and temperatures are calculated from the Doppler shifts.

经分析处理的数据产品展示了南极莫森站（Mawson Station）与戴维斯站（Davis Station）上方、周边及两站之间的高空风速、风向与气温。数据采集高度大致与绿色、红色极光的出现高度相符。原始数据通过高灵敏度CCD（Charge-Coupled Device）相机以摄影方式记录，采集内容为气辉或极光光线在法布里-珀罗干涉仪（Fabry-Perot Interferometers）中形成的干涉条纹组。月球、恒星等其他光源发出的光线已被滤除。通过干涉图样的极细微变化，可推算出光线波长的多普勒频移。基于该多普勒频移，可计算得到风速、风向与气温。如需了解更多详情，请访问：http://www.antarctica.gov.au/about-antarctica/environment/atmosphere/studying-the-atmosphere/studying-the-thermosphere-with-fabry-perot-spectrometers。本数据集产品为AAS 4130号项目的研究成果，是“南极上空热层中性风与气温”数据集系列的首批发布内容。
