Streamflow drought hazard indicators for monitoring drought hazard for human water supply and river ecosystems at the global scale (WaterGAP 2.2d, WFDEI-GPCC)

1) Streamflow drought hazard indicators (SDHIs) as computed by WaterGAP 2.2d (climate data WFDEI-GPCC) for the whole globe except Antarctica, spatial resolution: 0.5°, monthly data for the reference period 1986-2015:

Indicators of drought magnitude: SSI1, SSI12, EP1, RDQI1

Indicators of drought severity:

CDQI1-Q50, CDQI1-Q50_f, CDQI1-Q80, CDQI1-Q80_f, CDQI1-Q80-HS, CDQI6-Q80, CDQI6-Q80_f,

CDQI1-WUs, CDQI1-WUs-EFR, CDQI1-WUs-EFR_f,

CEP1(20%), CEP1(20%)_f, CRDQI1(-50%), CRDQI1(-50%)_f

2) WaterGAP grid cell IDs ("arcid") with longitude and latitude:
