Dobson spectrophotometer instruments are located at Lauder (45.04oS, 169.68oE), New Zealand, and at Arrival Heights (77.82oS, 166.65oE), Antarctica. Archives of the measurements are maintained at NIWA, Lauder, and in various international data archives. A combined data set of satellite-based total column ozone measurements providing global coverage is maintained at NIWA using measurements from a variety of satellite-based instruments including TOMS, GOME, SBUV, and OMI. Monitoring total column ozone levels above New Zealand and Antarctica. Validating satellite-based total column ozone measurements. The global satellite-based data set is used to set ozone changes over New Zealand in a global context. Measurements at Lauder are representative of ozone changes over New Zealand as a whole. Measurements at Arrival Heights are representative of the Antarctic ozone hole when measurements are made within the winter polar vortex. The satellite-based observations provide a global picture of ozone changes. onGoing pointOfContact NIWA ++ 64 4 386 0300 voice ++ 64 4 386 0574 facsimile 301 Evans Bay Parade, Hataitai Wellington 6021 New Zealand m.harvey@niwa.co.nz Mike Harvey Principal Scientist climatologyMeteorologyAtmosphere New Zealand and Antarctica ozone column Dobson Units satellite New Zealand Antarctica eng utf8 https://dc.niwa.co.nz/niwa_dc/srv/metadata/3ba9189d-64f3-47d6-8982-33031daa54ef WWW:LINK-1.0-http--metadata-URL Point of truth URL of this metadata record
