    Lidar technology is becoming a promising alternative for spray drift measurement to the labour and time-expensive methodologies based on the ISO 22866 standard. This paper presents last advancements in an eye-safe lidar ...
  • Measurement of pesticide spray drift with a specifically designed lidar system 

    Gregorio, Eduard; Torrent, Xavier; Planas, Santiago; Solanelles, Francesc; Sanz Cortiella, Ricardo; Rocadenbosch Burillo, Francisco; Masip, Joan; Ribes Dasi, Manel; Rosell Polo, Joan Ramon (2016-04-08)
    Article
    Open Access
    Field measurements of spray drift are usually carried out by passive collectors and tracers. However, these methods are labour- and time-intensive and only provide point- and time-integrated measurements. Unlike these ...
