II.1.4) Trumpas aprašymas:

This document is not a procurement announcement or a request for tender, but a detailed market survey, i.e. a request for information. 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. Laser calibration, with a He-Ne frequency-stabilised laser at 633 nm wavelength, or equivalent system, is critical to ensure the needed accuracy of the measurements. 3. Furthermore, the instrument should be able to resolve the sky scene into a software-defined set of sub-regions and compile a high-resolution Doppler spectrum of the source illumination originating from each one. These spectra should span a wavelength interval of around 10 pm. We foresee getting a SDI field-of-view divided into > 100 sub-regions and extending from the zenith down to about 25 to 30 degree elevation angles. The instrument will provide 2D observations around its installation site in Southern Finland, enabling the retrieval of neutral winds and neutral temperatures within a wide field of view (above elevation angles 25–30°), partly overlapping (at least for the red-line observations) that of a similar infrastructure installed in northern Fennoscandia called SDI-3D. We have the following questions: 1. Can you provide an instrument as described above? Please describe to what extent your instrument could match the requirements specified above. 2. Have you produced such an instrument for scientific purposes before? If so, please provide details (year, location, link to data repository if any...). 3. How would you plan to calibrate the instrument, and what accuracy can you obtain? Do you have experience with SDI calibration with frequency-stabilised laser systems? 4. What temporal resolution can reasonably be achieved with your instrument given its foreseen design and specifications? 5. What spatial resolution can reasonably be achieved with your instrument given its foreseen design and specifications? 6. What is the usable field-of-view angle to collect data with your instrument? 7. What is the foreseeable lead time until the instrument delivery in Finland? 8. What kind of housing solution is suitable for your instrument? Please describe the types of constraints that need be taken into account concerning its housing (e.g. geometrical dimensions, temperature control, connectivity, environmental disturbances)? 9. What would be a rough estimate of the cost for procuring the instrument (including its building and delivery to Finland, but excluding VAT)? 10. Would you be able to provide assistance with the installation, calibration, and maintenance of the instrument? Please describe to what extent and under which conditions. What would be the price of those services? 11. In addition, we would like to know your contract terms for offering these services. 12. Are you interested in taking part in the bidding competition, provided that one is arranged? Potential providers wishing to express interest in the procurement are invited to contact us and provide a description of the solution they could offer by answering the above questions at the latest on 31 Jan 2025 to maxime.grandin@fmi.fi, cc: kirsti.kauristie@fmi.fi. Request for additional information on the RFI must be sent to us at the latest on 15.1.2025 to the address to maxime.grandin@fmi.fi, cc: kirsti.kauristie@fmi.fi. The questions must be asked in English. Questions and responses are treated anonymously. Our additional information will be sent to everyone who will contact us about the planned procurement in time given above.
