Read full description

Ciudadanos Científicos es un proyecto local de ciencia, educación y tecnología, desarrollado por el Sistema de Alerta Temprana de Medellín y el Valle de Aburrá SIATA y financiado por el Área Metropolitana del Valle de Aburrá. El proyecto se encuentra en vigencia desde el año 2015, cuando algunos ciudadanos del Área Metropolitana decidieron, de manera voluntaria, tener en sus hogares o lugares de trabajo una "nube", es decir, un sensor de medición del aire de bajo costo que permite obtener mediciones puntuales, minuto a minuto, de la temperatura, humedad y PM 2.5. Contar con una red de esta naturaleza ha permitido enriquecer investigaciones que soportan decisiones, por ejemplo las tomadas durante las alertas naranja y roja por episodios críticos de calidad del aire, la construcción de políticas, y además, ha despertado la conciencia de los ciudadanos en su papel y responsabilidad para contribuir al cuidado y mejoramiento de la calidad del aire en la región.
