Previous studies have directly selected low emission factors (emission rate x leaf biomass density), resulting in an underestimation of isoprene emissions of 5 to 14.5 Tg C yr-1;
In the past, the emission factors (emission rate × leaf biomass density) selected directly were low, which resulted in the emission of isoprene underestimated by 5 − 14.5 TG Cyr − 1;
