Short summary
Here we present the iDirac, a new instrument capable of making isoprene measurements in remote and challenging environments. The iDirac is a customisable and rugged field instrument for investigating emissions of volatile organic compounds from vegetation. It has been tested here in a series of experiments to ensure a high degree of technical precision, accuracy and repeatability. This new instrument allows us to ask and answer new questions about the influence of vegetation on the atmosphere.
