Davis Aerodrome Project (DAP) – Air Quality Monitoring Data

The Davis Aerodrome Project (DAP) collected a range of environmental survey data over several field seasons to support a comprehensive environmental assessment of the proposed aerodrome. This data includes flora, fauna, soils, lake ecosystem, nearshore, marine, air quality and meteorological information which has been collected by a number of different methods, and extends across the current Davis Station, proposed aerodrome and supporting infrastructure footprint (Ridge Site), previous sites considered for the aerodrome (Heidemann Valley, Adams Flat), as well as locations across the Vestfold Hills away from any of the proposed developments. This dataset contains air quality data collected for the Australian Antarctic Division’s Davis Aerodrome Project (DAP). Four monitoring stations (AQ1, AQ2, AQ3, AQ4) were established across the Davis Region in the 2018/19 field season in areas of interest to the Year Round Aviation Access scoping project and later the DAP. Sites include one at Davis Research Station, one in the Adams Flat area, one on the DAP Ridge site and one site located remotely near Brooks Hut in Long Fjord. Automated Vaisala instruments were installed at all four sites to monitor selected gas and particulates. The instruments installed and variables being monitored at all sites are listed below. -    Vaisala AQT 420*    Particulate matter (2.5 and 10 microns)*    Gases SO2, NO2, O3, CO-    Vaisala GMP252 *    Gas CO2-    Datalogger DT4DT82E dataTakerBattery voltage, air temperature, pressure and humidity were also recorded by the instruments.The equipment was programmed to measure and record each of the monitored variables daily, at 15-minute intervals during the summer (16 Sept 00:15 – 15 April 23:45). During the winter months, 16 April to 15 Sept, the instruments were programmed to sample at hourly intervals over a two-day period, every 14 days. This reduced level of monitoring was required due to battery capacity over the winter. Data was downloaded from the Datalogger at each site every 4-6 weeks. Once data were collected they were added to the existing dataset for that site and the graphical analysis updated. -    AQ1 – Latitude: -68.575622 Longitude: 77.96532-    AQ2 – Latitude: -68.55417 Longitude: 78.014548-    AQ3 - Latitude: -68.551938 Longitude: 78.053264-    AQ4 - Latitude: -68.54678 Longitude: 78.195624-    AQ1 - Start date: 2019-01-28 - Stop date: 2019-04-07-    AQ2 – Start date: 2019-01-30 - Stop date: 2019-04-07-    AQ3 - Start date: 2019-01-30 - Stop date: 2019-04-07-    AQ4 - Start date: 2019-02-07 - Stop date: 2019-04-07
