Diurnal branch-level emission rates of the biogenic volatile organic compound (BVOC) isoprene were determined at the University of Michigan Biological Station for the tree species red oak (Quercus rubra) in 2003. Emission rates were determined as a function of temperature, photosynthetically active radiation (PAR), and leaf dry weights. Isoprene emission rates were also provided after temperature and PAR correction.
