… In Section 5, we present an improved global gridded dataset of the SPEI. Finally, in
Section 6 we present a new real-time global drought monitoring system based on the SPEI. …

… This study describes a global drought monitoring system based on the SPEI calculated
from the ERA5 dataset. The information is provided at a 0.5 longitude and latitude spatial …

… It is therefore important to have in place adequate drought assessment and monitoring tools
… the SPI and SPEI, this study seeks to compare the SPI and SPEI in characterizing droughts …

… , the indices of SPEI, SPI and RDI were investigated and the SPEI index as a multiscalar …
to detect, monitor, and explore the consequences of global warming on drought conditions in …

… with currently available global drought indices such as the SPEI-CR… SPEI datasets can be
used for drought monitoring and assessing drought severity and duration at a local and global …

… We derived trends in drought frequency and severity, separately for SPI and SPEI at a 12-month
accumulation scale, which is usually related to hydrological droughts. Results show …

… To determine the difference in timescale of SC-PDSI and SPEI drought monitoring, we did
correlation analysis of SC-PDSI and SPEI on different timescales. The results showed that the …

… Note that to obtain a global average assessment of the drought trends, we did not use the
standardized version (eg SPI, SPEI or SEDI) and instead focused on the evolution of the …

… Finally, they reported that SPI and SPEI have the same capacity to understand drought in
their studies; therefore, SPI or SPEI methods can be used in drought monitoring in drought-…

… Along with 4 and 6 months SPEI, in this study, we have calculated 9 and 12 months SPEI
to understand the drought condition in the region in a longer timescale. The area under …
