“…Many studies have examined dust transport to the WNAO and Caribbean regions with satellite and reanalysis data, ground observations, and transport modeling (e.g., Chen et al, ; Colarco et al, ; Husar et al, ; Kandler et al, ; Zuidema et al, ). Although to the south of this study's domain of the WNAO, the Puerto Rico Dust Experiment is especially noteworthy as it represented a very thorough campaign to characterize mineral aerosol properties and cycling over the WNAO (Colarco et al, ; Levy et al, ; Reid, Reid, et al, ; Reid, Kinney, et al, ).…”

Atmospheric Research Over the Western North Atlantic Ocean Region and North American East Coast: A Review of Past Work and Challenges Ahead

Decades of atmospheric research have focused on the Western North Atlantic Ocean (WNAO) region because of its unique location that offers accessibility for airborne and ship measurements, gradients in important atmospheric parameters, and a range of meteorological regimes leading to diverse conditions that are poorly understood. This work reviews these scientific investigations for the WNAO region, including the East Coast of North America and the island of Bermuda. Over 50 field campaigns and long‐term monitoring programs, in addition to 715 peer‐reviewed publications between 1946 and 2019, have provided a firm foundation of knowledge for these areas. Of particular importance in this region has been extensive work at the island of Bermuda that is host to important time series records of oceanic and atmospheric variables. Our review categorizes WNAO atmospheric research into eight major categories, with some studies fitting into multiple categories (relative %): aerosols (25%); gases (24%); development/validation of techniques, models, and retrievals (18%); meteorology and transport (9%); air‐sea interactions (8%); clouds/storms (8%); atmospheric deposition (7%); and aerosol‐cloud interactions (2%). Recommendations for future research are provided in the categories highlighted above.

In addition, Ginoux et al 2012 [40] used C as 10 −6 g s 2 m −5 for topographic erodibility and C = 1.9 × 10 −6 g s 2 m −5 for soil erodibility derived from MODIS Deep Blue Level 2 satellite product.…”

Between 11 and 15 February 2019, a dust storm originating in Central Australia with persistent westerly and south westerly winds caused high particle concentrations at many sites in the state of New South Wales (NSW); both inland and along the coast. The dust continued to be transported to New Zealand and to Antarctica in the south east. This study uses observed data and the WRF-Chem Weather Research Forecast model based on GOCART-AFWA (Goddard Chemistry Aerosol Radiation and Transport–Air Force and Weather Agency) dust scheme and GOCART aerosol and gas-phase MOZART (Model for Ozone And Related chemical Tracers) chemistry model to study the long-range transport of aerosols for the period 11 to 15 February 2019 across eastern Australia and onto New Zealand and Antarctica. Wildfires also happened in northern NSW at the same time, and their emissions are taken into account in the WRF-Chem model by using the Fire Inventory from NCAR (FINN) as the emission input. Modelling results using the WRF-Chem model show that for the Canterbury region of the South Island of New Zealand, peak concentration of PM10 (and PM2.5) as measured on 14 February 2019 at 05:00 UTC at the monitoring stations of Geraldine, Ashburton, Timaru and Woolston (Christchurch), and about 2 h later at Rangiora and Kaiapoi, correspond to the prediction of high PM10 due to the intrusion of dust to ground level from the transported dust layer above. The Aerosol Optical Depth (AOD) observation data from MODIS 3 km Terra/Aqua and CALIOP LiDAR measurements on board CALIPSO (Cloud-Aerosol LiDAR and Infrared Pathfinder Satellite Observations) satellite also indicate that high-altitude dust ranging from 2 km to 6 km, originating from this dust storm event in Australia, was located above Antarctica. This study suggests that the present dust storms in Australia can transport dust from sources in Central Australia to the Tasman sea, New Zealand and Antarctica.

“…Chen et al 2016 [25] studied the transport of dust event in March 2010 from Taklimakan and Gobi deserts across China to Korea and Japan using WRF-Chem model, they used Aerosol Optical Depth (AOD) data from AERONET ground network and vertical aerosol extinction coefficients from CALIPSO satellite. [26] recently studied intercontinental dust transport from two dust storm events in 2015 in North Africa (Sahara-Sahel) and Asia (Taklamakan) deserts to the East and West coast of the U.S. using AOD from MYD04-3k (Aqua) Moderate Resolution Imaging Spectroradiometer (MODIS) level 2 products, AI (Aerosol Index) or Aerosol Optical Thickness (AOT) derived from satellite measurements such as GOES (Geostationary Operational Environmental Satellite system) Aerosols/Smoke Product (GASP), OMI (Ozone Monitoring Instrument) onboard Earth Observing System (EOS), VIIRS (Visible Infrared Imaging Radiometer Suite) aboard the Suomi National Polar-orbiting Partnership (Suomi-NPP). In addition, lidar-measurement of aerosol vertical profile by CALIOP onboard CALIPSO satellite, ground based AERONET of solar radiation and air quality monitoring stations as well as MERRA-2 aerosol reanalysis were also used to characterise the source and long-range transport (LRT) pattern of dust events from North Africa and Asia to the U.S.…”

Between 11 to 15 February 2019, a dust storm originating from Central Australia with persistent westerly and south westerly winds caused high particles concentration at many sites in the state of New South Wales (NSW), both inland and along the coast. The dust continued on to New Zealand and to Antarctica in the south east. This study uses observed data from air quality monitoring stations in NSW and New Zealand, MODIS 3km AOD (Aerosol Optical Depth) product from Terra/Aqua and lidar aerosol profile from CALIPSO (Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations) satellite data, and the Weather Research Forecast WRF-Chem model based on GOCART-AFWA (Goddard Chemistry Aerosol Radiation and Transport – Air Force and Weather Agency) dust scheme and GOCART aerosol and gas-phase MOZART (Model for Ozone And Related chemical Tracers) chemistry model to study the long-range transport of aerosols for the period 11 to 15 February 2019 across eastern Australia and onto New Zealand and Antarctica. Wild fires also happened in northern NSW at the same time and their emissions are taken into account in WRF-Chem model by using Fire Inventory from NCAR (FINN) as emission input. Modelling results by the WRF-Chem model show that for the Canterbury region of South Island of New Zealand, peak concentration of PM10 (and PM2.5) as measured on 14 February 2019 at 05:00 UTC at the monitoring stations of Geraldine, Ashburton, Timaru and Woolston (Christchurch), which are more than 100km from each other and at Rangiora, Kaiapoi about 2 hours later, correspond to the prediction of high PM10 due to intrusion of dust to ground level from transported dust layer above. The Aerosol Optical Depth (AOD) observation data from MODIS Terra/Aqua and CALIOP lidar measurements on board CALIPSO satellite also indicate that high altitude of dust, originated from this dust storm event in Australia, was located above Antarctica. This study suggests that at present dust storms in Australia can transport dust from sources in Central Australia to the Tasman sea, New Zealand and Antarctica. This process has been going on for at least the last 170k years as indicated by dust found in ice cores from Antarctica and sediment records in the Tasman Sea.
