1. Project: QUILT 2. Station name: Andoya (Norway) 69.3N, 16E 3. Research group: Norwegian Institute FOR Air Research (NILU) 4. Investigators name: Kjersti K. TØRNKVIST (kjersti.toernkvist@nilu.no) 5. Instrument: UV-visible spectrometer 6. Activities carried out since last report: -daily morning and evening measurements of ozone an NO2 vertical coloumns (90 SZA) -daily morning and evening measurements of BrO and OClO differential slant coloumn densities (90-80 SZA) (if no observation at 80 SZA, a fixed reference spectrum at 80 SZA is used) 7. Preliminary results: Vertical column ozone (Dobson units) and NO2 (1e15 mol/cm2) Differential slant column densities BrO (1e14 mol/cm2) and OClO (1e13 mol/cm2) This is preliminary data, and thus should not be used in scientific publications or presentations without the consent of the principal investigator.
