Fig. 4: Dust emission and its change over different land cover types.
From: Drivers of recent decline in dust activity over East Asia
a Regional accumulated dust emission (Tg yr−1) averaged over 2001–2017 over the whole Eastern Sources and contributions from the barren lands, grasslands, and croplands, respectively. b Reduction of dust emission (Tg yr−1) during 2010−2017 relative to 2001 over the whole Eastern Sources and contributions from the barren lands, grasslands, and croplands, respectively. The results shown in (a) and (b) are from the baseline experiment. Reduction of dust emission (Tg yr−1) during 2010–2017 relative to 2001 over (c) barren lands and (d) grasslands due to surface wind (Wind), leaf area index (LAI), soil moisture (SOILM), and all these three factors, respectively. For comparison, the relative contributions from different land types (a, b) or different influencing factors (c, d) are also provided at the top of each bar.
