SECTION `{"section":"Abstract"}`	Reliable future climate projections and water deficiency assessments require precipitation observations that are both spatially comprehensive and temporally complete
TRANSCRIPTION `{"section":"Abstract"}`	The study evaluates precipitation-gauge coverage because reliable climate projections and water-deficiency assessments require observations that are spatially comprehensive and temporally complete. It evaluates 221,483 internationally ex...
SECTION `{"section":"Spatiotemporal variability of global gauge records; Comparison of gauge density with WMO requirements"}`	Between 1900 and 2022, observations from 221,483 accessible precipitation gauges were recorded
TRANSCRIPTION `{"section":"Spatiotemporal variability of global gauge records; Comparison of gauge density with WMO requirements"}`	Between 1900 and 2022, the study compiled observations from 221,483 accessible precipitation gauges, of which 63.2%, or 139,901, remained active within the past 30 years. It identified 38,203 long-term-record stations, defined as records...
SECTION `{"section":"Priority areas under historical period; Priority areas under future scenarios"}`	Globally, approximately 25% of land areas are identified as high priority for siting new gauges
TRANSCRIPTION `{"section":"Priority areas under historical period; Priority areas under future scenarios"}`	Using a priority score for siting new gauges, the study identifies approximately 25% of global land as high priority under historical precipitation information from 1900 to 2022. High-priority land shares include 38.7% of Africa, 32.3% o...
