Title

DustWatch Database

Abstract

Dust data in an indicator of soil and catchment health. The assumption is that if wind erosion is occurring and dust is being transported away from the site, then the soil is degrading.

Dust data is stored in the DustWatch data base. Dust concentration measurements are sourced from the DustWatch Node network described in Leys et al. 2008 (http://www.environment.nsw.gov.au/dustwatch/). The PM10 data are sampled with DustTrak sensors, a portable, battery-operated laser photometer that gives real-time mass concentration within the particle-size range 0.1 to approximately 10 micrometres. The sensors are enclosed in the manufacturer's field enclosure and have been modified to operate remotely and with minimal maintenance. One minute data is averaged to hourly values.

Quality and validity

Lineage

Data processing and quality control of the data includes:; * Subtraction of the clean air reading from the PM10 reading.; * Calculation of the mean weighted dust concentration of each reading. Due to the non-standard sample interval of between 15 and 1 minutes, values are weighted to 1 minute values. This is because the 1 minute data is later averaged to hourly readings.; * Checking each record is within the range of the instrument.; * Classifying the aerosol reading as dust, smoke or fog. Automatic scripts within MADD classify the hourly averaged data as follows:; o Fog classification is evoked when relative humidity is > 90%, wind speed is , 10 km/h and temperature is 10 km/h and fires are known to be upwind.; o Dust when conditions are not that of smoke or fog; * A manual checking is then performed on the hourly data to check the automatic classification. ; * No systematic quality control of the BoM AWS data is undertaken.

DQ Completeness Commission

Effective date

Explanation

Data completeness varies between sites from 90 to 100%. Data is downloaded daily from each DustWatch node. Dust concentration of material less than 10 microns (PM10) is measured with DustTrak instruments. ;;Modifications to instrument include:; Heat shield to reduce temperature extremes and keep the instrument within operating specifications.; Solar panel and battery.; Modem for communications.; Data logger to synchronise the reading to on the hour; 15, 30 and 45 minutes past the hour. This is done to synchronise the data with BoM weather data which is generally taken on the hour.; The data logger turns the system on every 15 minutes and records a one minute reading. If the PM10 reading is greater than 25 micrograms (ug/m3) then the instrument stays on until the reading is less than 25 micrograms (ug/m3).; A zero-filter (clean air) has been installed and in controlled by the logger and a solenoid value. Before each 15 minute reading a 1 minute clean air sample is taken. This is used later on to calibrate the PM10 readings.;;Quality control of the instrument includes:; A monthly on-site calibration of the instrument to reset the zero value for clean air.; Monthly cleaning of the inlet and solar panel and general cleaning of instrument.;* Returning the sensor to the manufacturer every year for routine calibration and maintenance.
