Saber que los árboles enfrían en tres dimensiones ayuda a decidir dónde plantar y cómo diseñar barrios más vivibles. Para quien vive en una ciudad como Buenos Aires o Córdoba, la sombra y el verde dejan de ser decoración y pasan a ser infraestructura. Enfriar la ciudad también es una decisión política.","quienFirma":"Preprint en bioRxiv (investigadores en Roma, Italia)","confianza":"preprint","consulta":{"pregunta":"¿El arbolado de tu barrio alcanza para refrescar?"}},"sello":{"hash":"1d5bfc5cfb83f22f479c30e1e6ca91f02501288d0880c378b1a2df748be4404e","sello":"779c4974b95e4373a1d27c0926ad765016051bf81c7c7c00121e6579e282752f","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6590219,"aleatorio":"51cbd4943e8cb3fd4f3b6a284c94f918d6e5a8e08289471b968b552ec8b3f6de","tiempo":"2026-10-27T21:46:30.000Z"},"nist":{"cadena":2,"pulso":2002043,"salida":"462E5A4EB267B249AECB5DD9140D97F890206341D81BD743EF05759E6C21A153B272C9545B206734CF3F8A5EF9DAD09DD7066B821552F19DD652F1BD05895FC9","tiempo":"2026-10-27T21:45:00.000Z"},"noAntes":"2026-10-27T21:46:30.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Oct 27 21:47:01 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"Bird-assisted sampling of air temperature reveals three-dimensional cooling effects of urban vegetation","descripcion":"Air temperature in cities is highly variable horizontally and vertically, reflecting the complexity of the urban landscape. Yet, studies of urban temperature still depend largely on ground-based meteorological stations and satellite-derived surface temperature products, both of which provide limited information on near-surface air conditions and vertical structure. We tested a bio-assisted monitoring approach to characterise fine-scale three-dimensional patterns of summer air temperature in the city of Rome, Italy, using homing pigeons (Columba livia) equipped with lightweight GPS loggers air-temperature sensors.
