GRACE satellite-based drought index indicating increased impact of drought over major basins in China during 2002-2017
Agricultural and Forest Meteorology(2020)
摘要
•Proposed GRACE-DSI removes the effect of non-climate factors on drought and reflects true drought conditions.•Results indicate an increase in duration, severity, and frequency of drought in most basins during 2002–2017.•GRACE-DSI exhibits significant advantages in capturing the drought process over other drought indices.
