  "excerpt": "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 spanning more than 30 years with less than 10% missing data. Only 16,491 of 119,731 operating stations in 2022 were long-term-record stations. Europe had the largest share of long-term-record stations, while Africa had very low total and long-term station densities. Comparing gauge density with World Meteorological Organization requirements, only 13.4% of global land met recommended station density during 1900–2022, and only 1.9% met the requirement when long-term-record stations alone were considered. The analysis attributes insufficient density to limited public data accessibility, high construction and maintenance costs, data-quality challenges and lower prioritization in regions perceived as having limited climate risks.",
