Paper Abstract

Ozone loss in the stratosphere, especially its drastic reduction in the Antarctic, has been the main driver for the middle atmosphere research during the last two decades [1]. A good understanding of the relevant processes has been obtained and the dynamical-chemical models are mature enough so that credible predictions of the future of the ozone layer can be made. However, i.e. the effect of the climate change on the pole-to-pole circulation is not clear. The proposed Spectral Imaging of Middle Atmosphere for Climate Change (SIMACC) concept aims to significantly contribute to answering the many open questions in understanding the climate change. The main objective of the proposed SIMACC mission is to investigate the changes the middle atmosphere will undergo during the ongoing rapid climate change [2]. VTT has developed novel Fabry-Perot –based hyperspectral imagers that are to be used in SIMACC [3]-[5]. In these spectral imagers the Fabry-Perot interferometer (FPI) is used at multiple orders simultaneously with each order matched to a specific pixel filter. In the visible (VIS) and very near infrared (VNIR) wavelengths (400 – 1100 nm) the standard Bayer patterned RGB color sensor was used providing the possibility for measuring three spectral bands with one exposure.
