1. Surface ozone concentration from an TEI instrument at Arrival Heights [K085_2002_2014_NZ_1]
A TEI instrument was installed at Arrival Heights to monitor boundary layer concentration of surface ozone levels with an ultraviolet absorption measurement. Ambient air is pumped through a cell and ...


2. Tropospheric Ozone Depletion and Bromine Explosions [K084_2006_2013_NZ]
Tropospheric ozone depletion events during the Antarctic spring of 06/07 and 07/08 were observed. DOAS measurements of near surface BrO and O3 concentrations were made at three locations: Cape Bird ...


3. RICE: Roosevelt Island Climate Evolution Project - Automatic Weather Station Data [K049_2010_2012_NZ_2]   PARENT DIF
RICE is an international collaboration between New Zealand, USA, Denmark, United Kingdom, Germany, Australia, Italy and China. The aim of the project is to recover a 750 m deep ice core from Roosevelt ...


4. Annual measurements of atmospheric methane concentrations and isotopic ratios from Arrival Heights, Ross Island [K087_1989_2012_NZ_1]
The atmospheric trace gas, methane (CH4), affects the radiative heat balance of the earth. The sources of atmospheric methane are not well understood. Large air samples (1000-1400 litres) of methane ...


5. Surface ozone concentration from an TEI instrument at Arrival Heights [K085_2002_2012_NZ_1]
A TEI instrument was installed at Arrival Heights to monitor boundary layer concentration of surface ozone levels with an ultraviolet absorption measurement. Ambient air is pumped through a cell and ...


6. Annual measurements of atmospheric carbon monoxide concentrations and isotopic ratios from Arrival Heights, Ross Island since June 1991 [K087_1991_2008_NZ_1]
Carbon monoxide (CO) is a trace gas in the atmosphere. Although it occurs naturally in the atmosphere at very low concentrations, it may contribute to the greenhouse effect and concentrations are ...


7. Atmospheric air samples from aboard supply aircrafts operating between Christchurch, New Zealand and McMurdo Sound investigating the atmospheric chemistry and reactions between carbon monoxide, methane and ozone [K087_1996_1998_NZ_1]
Large whole air samples collected from a compressor system aboard the supply aircrafts operating between Christchurch and McMurdo incorporated measurements of ozone. In association with concentration ...


8. Measurements of carbon monoxide concentrations and isotopic ratios from the atmosphere via equipment aboard supply aircrafts operating between Christchurch, New Zealand and McMurdo Sound [K087_1991_2008_NZ_2]
Carbon monoxide (CO) is a trace gas in the atmosphere. The use of the radioactive isotope 14C in carbon monoxide is useful for determining the oxidative capacity via oxidation by hydroxyl (OH). Large ...


9. Measurements of methane concentrations and isotopic ratios from the atmosphere via equipment aboard supply aircrafts operating between Christchurch, New Zealand and McMurdo Sound [K087_1989_2008_NZ_2]
The atmospheric trace gas, methane (CH4), affects the radiative heat balance of the earth. Measurements of the carbon and hydrogen isotopes in atmospheric methane are used to relate this climatically ...


10. Measurements of the mixing ratios of the C2-C10 non-methane hydrocarbons from Arrival Heights since 1990 [K087_1990_2008_NZ_1]
A large variety of nonmethane hydrocarbons (NMHCs) are found throughout the troposphere in varying concentrations. The reaction of a NMHC with the hydroxyl (OH) molecule causes atmospheric oxidation. ...


11. The concentration of combustion engine particulates, the organic fraction of the particulates and the sources of the particulates identified by isotopic analysis from snow and ice samples near Scott Base [K011_2000_2001_NZ_1]
The likely sources of organic pollutants in Antarctica are aircrafts, generators and vehicular emissions. Engines and generators emit organic rich particulates due to incomplete fuel combustion that ...


12. Atmospheric measurement from four sites in the Ross Sea Region investigating gases, aerosol properties and local weather conditions [K173_1987_1990_NZ_1]
Gases, aerosol properties and local weather was studied at sites around Ross Island and in McMurdo Sound as part of a programme to describe the properties of the atmospheric aerosol (and gases), to ...


13. Surface ozone concentration from an TEI instrument at Arrival Heights [K085_2002_2008_NZ_1]
A TEI instrument was installed at Arrival Heights to monitor boundary layer concentration of surface ozone levels with an ultraviolet absorption measurement. Ambient air is pumped through a cell and ...


14. Surface ozone concentration measurements using a surface ozone monitor from Scott Base [K085_1996_2003_NZ_1]
The boundary layer concentration of ozone was measured with a Dasibi ozone instrument that monitors surface ozone with an ultraviolet absorption measurement. Ambient air is pumped through a cell ...


15. Tropospheric Ozone Depletion and Bromine Explosions [K084_2006_2007_NZ]
