Abstract:

This article introduces the instrument structure of Fabry-Perot Interferometer (FPI), the capacity of wind measurements, the process of data reduction procedure, data quality control plan and data validation works which was deployed at Kelan Meteorological Bureau (39°N, 112°E) in Shanxi, China. The FPI of Kelan has the ability to measure the Doppler shift of airglow emissions (OH892.0nm, OI557.7nm, OI630nm) at mesopause and in thermosphere to derive horizontal wind vector and atmosphere temperature at heights of 87km, 97km and 250km, respectively. From late of 2011 to middle of 2014, a series of more than 6000 measurements at each height are derived according to manufacture data quality criteria. In data validation works, the Horizonal Wind Model (HWM) was applied to do the cross-comparison with Kelan FPI's observations. The comparisons show that the general trends of Kelan FPI's wind measurements are consistent with HWM's outputs and there exists difference of seasonal variation. The comparison results prove that the data quality control plan works and the measurement accuracies are 5.7m·s-1 at 87km, 1.3m·s-1 at 97km and 4.1m·s-1 at 250km height. In general, Kelan FPI's wind measurements are reliable and useful for investigations of the wind morphology in the mesosphere and thermosphere.
