  1. Hourly surface wind speed (in terms of friction velocity) and soil moisture (SOILM) as well as daily leaf area index (LAI) are used. For the experiment with one individual factor set to the values as in 2001, the seasonal variations of this factor are still considered and only its interannual variations are excluded. Also shown in the last two columns are annual dust emission over Eastern Sources for 2001 and 2010–2017, respectively.
