“…The Arabian Gulf is surrounded by desert ecosystem characterized by active aeolian conditions [6,7]. Land degradation and extended drought periods act as a major activator of SDS in deserts [8]. There are substantial amounts of dust grains that may be driven thousands of kilometers from their origin [9], and it has been valued that aeolian dust derived from soil erosion gives annually around 500 million tons of particulates into the atmosphere [10].…”

Dust is a common weather phenomenon in the Arabian Gulf, which has severely affected economy and health. Sand and dust storms (SDS) trajectories in the Arabian Gulf were temporally and spatially monitored from March 2000 to March 2017. Eight major SDS trajectories were detected from satellite images. The dust storms trajectories were categorized according to shape and size into three main types with 12 subtypes in the region. The annual transported dust amount into the Arabian Gulf was estimated by 89.1 million metric tons, which is about 10,330 metric tons per cubic kilometer of water volume. In comparison to other seas and oceans, the amount of dust deposited into the Arabian Gulf water body volume is the highest. Dust deposited in the coastal regions within the Arabian Gulf are originated from Mesopotamian Flood Plain (MFP), Ahwaz (HZ), Ahwar (HR) and Baluchistan Desert (BSH) and characterized by physical parameters and composition. Such physical characterization of the trajectories of SDS, and of the properties of particles transported in the Arabian Gulf can be helpful to assess and mitigate the environmental impact of future similar events.

“…Several other studies have showed that persistent dust activity days were mostly associated with cold fronts [84,87,88]. It is highly probable that dusts are transported from the central Australian deserts by winds associated with these cold fronts.…”

“…In Figure 5, there are several DWN that sit outside the 90% confidence intervals (CI). For example, Coombah and Lake Victoria have permanent native vegetation with trees around them, Euston and Pooncarie are in farming areas with sandy soils, and Tibooburra is located down wind of Australia's largest dust source, the Lake Eyre Basin [12,52,53]. All of these factors add to the spread in the data.…”

“…It took 13 years to increase the use of best land management practices from 16 to 66% in the Mallee in Australia [11]. Measuring change therefore requires long term monitoring that captures not only management change, but also the seasonal climate variations [12]. Critical to all monitoring is that measurements are at the appropriate spatial and time scales.…”

Dust emissions contribute significantly to atmospheric processes impacting the functioning of various earth and human systems. The question is often asked "how much dust is acceptable?" From a land management perspective, the aim is to reduce the degradation effects of wind erosion over time.To do this, we need to know the range of dust activity over a long time period and to set a target that shows a reduction in dust activity. In this study, dust activity is described by the number of dust hours per July to June period (dust storm year, DSY). We used the DustWatch network of high resolution particulate matter less than 10 µm (PM10) instruments to characterise the dust climatology for a ten year period for western New South Wales (NSW), Australia. The ten year study period covered one of the driest and wettest periods in south-eastern Australia, providing confidence that we have measurements of extremes of dust (0 to 412 h/DSY), rainfall (98 to 967 mm/DSY), and ground cover (0 to 99% of area/DSY). The dust data are then compared to remotely sensed ground cover and measured rainfall data to develop targets across a rainfall gradient. Quantile regression was used to estimate the number of dust hours for a given DSY rainfall at 21 DustWatch Nodes (DWN). The 75th percentile is used to determine the target number of dust hours for a ten year average DSY. The monitoring network clearly identified locations of high dust activity and changes in dust and ground cover that are associated with rainfall. The dust hour targets for NSW indicated that for every 100 mm increase in DSY rainfall (between 250 and 650 mm) there is a 10 h decrease in dust hours. The dust target enables us to evaluate whether wind erosion is decreasing with time for sites with different rainfall.
