Article Synopsis
- Two major super dust storms in March 2021 struck Mongolia and Northern China, resulting in significant fatalities and economic losses.
- Accurate forecasting of these storms is crucial, and soil moisture levels play a key role, although they can vary significantly in desert regions.
- Model experiments revealed that different soil moisture datasets greatly affect dust emission estimations, with the ERA5 dataset providing the best simulation, highlighting the Mongolian Gobi Desert as the primary dust source contributing to pollution in neighboring regions.
Satellite NO observations have been widely used to evaluate emission changes. To determine trends in NO emission over China, we used a method independent of chemical transport models to quantify the NO emissions from 48 cities and 7 power plants over China, on the basis of Ozone Monitoring Instrument (OMI) NO observations during 2005 to 2015. We found that NO emissions over 48 Chinese cities increased by 52% from 2005 to 2011 and decreased by 21% from 2011 to 2015.
