    Monitoring in the rainforest biome of the Eden Project

    We are pleased to be helping young people get interested in science by providing a Graywolf AdvancedSense to the Institute for Research in Schools. IRIS have set up the sensor in the rainforest biome of the Eden Project, where it will gather CO, NO2, O3, and SO2 data to be analysed by budding scientists at IRIS’ partner schools.

     Note the custom enclosure and mesh to keep the insects out!

    Smogmobile Experiment: Diesel versus petrol and petrol-hybrid

    The Smogmobile followed each vehicle at a distance of roughly 15 metres as they drove up and back down Cowcombe Hill, near ET’s office in Stroud. As these time series graphs clearly show, the levels of NO2­ measured whilst following the diesel Land Rover were significantly higher than those seen while following one of our hybrid Mitsubishi 4x4s. This goes to prove that changing our engineer fleet of cars to the hybrid Mitsubishis was certainly a good move!”

    The Smogmobile Measures Southamptons Air for the BBC on Inside Out South

    ETs smogmobile is out in Southampton again helping measure the amount of NO2 in the air from rush hour traffic.

    Even though it's a wet blustery day, when typically levels would be low, levels of 200 ug per cubic meter upwards were found which if they were consistantly reached for a period of an hour or so, they would breach the UK guidelines values for NO2. ET's Air Quality expert, Duncan Mounsor, explains how people living in more congested areas are more at risk.
