  1. Measurements of ozone columns in different atmospheric layers over St. Petersburg (Russia) using ground-based FTIR spectrometer in comparison with IASI satellite instrument Metop A Launched on October 19, 2006 Altitude 817 km Orbit Polar sun-synchronous Inclination 98.7 to the equator Local time 09:30, descending orbit Repeat cycle 29 days (412 orbits) IASI Fourier transform spectrometer Spectral range 645 to 2760 cm−1 Spectral resolution 0.3–0.5 cm−1 (0.5 cm−1 apodized) Radiometric noise <0.1–0.2K (650–1750 cm−1) (Ne1T at 280 K) 0.2–0.4K (1750–2500 cm−1) Field of view 50 km (3.33) at nadir, with 4 simultaneous pixels of 12 km Full swath width 2200 km (±48.3), 120 pixels Global Earth coverage 2 times per day We used the LISA retrieval algorithm for deriving the ozone profiles between 0 and 60 km for the region of 2 degrees around the Peterhof station in coincidence with FTIR-observation dates, and averaged profiles daily over all the pixels in the considered region.
