Methyl halide fluxes from rapeseed (Brassica napus) over its life cycle

Rapeseed (Brassica napus) was quantified as one of the important terrestrial natural emitters of methyl bromide (CH3Br) to the atmosphere. In this study, we planted rapeseed (B. napus \"Empire\") in the field (Oxford Tract, UC Berkeley) and measured weekly methyl halide fluxes (CH3Cl, CH3Br and CH3I) using static-chamber measurements. The meteorological and physiological data, including air tempearture, plant height, leaf area, flowering number, biomass were also recorded over the life cycle of rapeseed.
