用MTR/THEMIS可见光谱仪拍摄的云顶金星风图。I.仪器性能和初步结果
Venus wind map at cloud top level with the MTR/THEMIS visible spectrometer. I. Instrumental performance and first results
摘要：
太阳光在金星大气层的云顶散射，在可见光范围内，相当于67公里的高度。我们目前的多普勒速度测量进行的高分辨率光谱仪MTR的太阳望远镜THEMIS（泰德天文台，加那利岛）的钠D2太阳线（5890 <$）。由于多云天气，观测只持续了49分钟。然而，我们可以评估仪器的速度灵敏度，31米/秒每像素的1弧秒，并给出一个值的纬向风在赤道的振幅为151 +/- 16米/秒。
英文摘要：
Solar light gets scattered at cloud top level in Venus' atmosphere, in the visible range, which corresponds to the altitude of 67 km. We present Doppler velocity measurements performed with the high resolution spectrometer MTR of the Solar telescope THEMIS (Teide Observatory, Canary Island) on the sodium D2 solar line (5890 Å). Observations lasted only 49 min because of cloudy weather. However, we could assess the instrumental velocity sensitivity, 31 m/s per pixel of 1 arcsec, and give a value of the amplitude of zonal wind at equator at 151 +/- 16 m/s.
