            <gco:CharacterString>Data were obtained over two summer seasons (2018 and 2019). Analysers located in a field control unit were used to collect real-time NOx and O3 concentrations using an automated switching system. Field-based insect pollinator and flower visitation frequencies were observational. Brassica nigra plants were cut to ground level and measured in the lab to obtain yield and pollination metrics.</gco:CharacterString>
