This document does not oblige the Finnish Meteorological Institute to carry out the procurement. The information provided does not bind any party to the market survey. As part of a science project funded by the European Research Council, the Finnish Meteorological Institute is planning to purchase an all-sky type Fabry-Perot interferometer (hereafter called Scanning Doppler Imager, SDI). The instrument will measure neutral winds and neutral temperatures at two altitudes in the thermosphere by making use of green-line (558 nm) and red-line (630.0 nm) emissions. The former will provide measurements corresponding to an altitude of approximately 110 km, whereas the latter will provide measurements corresponding to an altitude of approximately 240 km. The principle of the measurement will be the quantification of the Doppler shift and broadening of the emission lines. The SDI system should fulfil the following list of technical specifications: 1. The instrument should be composed of a capacitance-stabilised etalon capable of piezoelectric separation maintaining both plates perfectly parallel to each other and scanning at 10 Hz or faster, a low-light imaging detector capable of sampling at the etalon gap scanning frequency and synchronised with the scan, and wide-angle fore-optics arranged to place a sharp image of the sky onto the detector. 2.
