Con datos ordenados y accesibles, cualquier científico puede seguir ese rastro a escala global. Para quien vive en un país con sequías y crecidas, eso se traduce en mejores pronósticos de lluvias y de disponibilidad de agua. Lo que hoy es un dato técnico termina decidiendo cuánto llega al grifo o al campo. Aun así, todavía falta saber cuánto cambian estos patrones con el clima.","quienFirma":"Universidad no especificada en la fuente","confianza":"divulgacion","consulta":null},"sello":{"hash":"5df53ec26d7b05b6b2bae5669bd562dfd4680167be67fb9c8f840a83e8b9d608","sello":"1dad731c27c40207d97fa32d03b5b08ba6c36f77679753347d41abbf94d48b4a","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6590290,"aleatorio":"abd984b73498b8ae77ea0bf39f9c9512c47d5e3154ebc0ff6d4e91c8ed7a8bfc","tiempo":"2026-10-27T22:22:00.000Z"},"nist":{"cadena":2,"pulso":2002078,"salida":"289C8BA74E331EE5DC98B8553CD5A56C0C203E910429A3859452EAE6739704DFAB104F4F99E99F3CCC445DA47BBE5B6B26C5CC33216216C05CFBCDE6A303DCE9","tiempo":"2026-10-27T22:20:00.000Z"},"noAntes":"2026-10-27T22:22:00.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Oct 27 22:22:20 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"Open database tracks Earth's water cycle by standardizing decades of satellite data","descripcion":"All water comes from somewhere. Researchers who want to know where it comes from rely on water isotopes, variants of water molecules with slightly different masses, as location identifiers. In particular, the specific ratio of heavy to light water isotopes is unique to the water's origin and processes it has undergone and can provide information on how water travels across the globe.","pubDate":"Tue, 27 Oct 2026 18:20:13 EDT","url":"https://phys.org/news/2026-10-database-tracks-earth-standardizing-decades.html"},"indexado":"2026-10-27T22:21:49.280Z"}}
