报告简介

    Observations show that Earth's climate has been warming. To study climate change, many ground-based and space-based instruments have been developed to observe Earth's land, air, water and ice. An imaging Fabry-Perot spectrometer (FPS) has been developed at York University to obtain accurate, detailed, and collocated measurements of atmosphere and to retrieve simultaneously surface pressure, aerosol information, and surface albedo from the measurements. One key subsystem of this spectrometer is a Fabry-Perot, which is driven by three piezoelectric actuators to achieve nanometer positioning. This instrument has been validated through two successful stratospheric balloon missions in September 2016 and April 2017. In this talk, the development of this instrument and some lessons learned from this mission will be presented.
