Challenge<\/span><\/h2><\/h1><\/div>The Balearic Air Quality Control Agency was looking to modernize its monitoring network to comply with the new Best Available Technologies (BAT) and the upcoming European Air Quality Directive.
\nIts goal was to deploy a hybrid system with reference stations and advanced sensors, which would allow it to expand coverage, maintain data accuracy and support urban policies such as the future Low Emission Zone (LEZ) in Palma de Mallorca.<\/p>\n<\/div><\/div><\/div>
Solution<\/span><\/h2><\/h1><\/div>To meet these objectives, dnota installed 10 Bettair nodes in the historic center of Palma. These sensors measure NO\u2082, NO, O\u2083, CO, PM\u2081, PM\u2082.\u2085, PM\u2081\u2080, as well as meteorological conditions. The strategically located nodes improve coverage and meet European requirements.
\nTests with reference stations yielded an ozone uncertainty of less than 25 % and an R\u00b2 greater than 0.85, confirming their reliability. An additional node was also installed at Palma Airport, consolidating the hybrid network that combines high accuracy and operational efficiency. <\/span><\/span><\/span><\/span><\/p>\n<\/div><\/div><\/div><\/div><\/div>![](\"data:image\/svg+xml,%3Csvg%20xmlns%3D%27http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%27%20width%3D%27700%27%20height%3D%27700%27%20viewBox%3D%270%200%20700%20700%27%3E%3Crect%20width%3D%27700%27%20height%3D%27700%27%20fill-opacity%3D%220%22%2F%3E%3C%2Fsvg%3E\")
