AB: Part of the Arctic Station for the Network for the Detection of Stratospheric Composition Change (NDACC) consists of O₃ sondes and the mid-IR high resolution solar viewing Fourier transform spectrometer (FTS) at Thule, Greenland (76.5N, 68.8W, 225masl). The FTS operates autonomously providing observations on 75 days per annum on average. O₃ profile retrievals using the optimal estimation (OE) technique from the FTS spectra have a typical degrees of freedom for signal (DOFS) of about 4.2. Column and vertical profiles of O₃ are compared between the FTS and sondes on days of coincident measurement. These ground-based O₃ measurements are then compared with data from the OMI, TES, MLS and HIRDLS sounders on AURA and the ACE FTS aboard SCISAT-1.
