[1]我们在HadGEM2地球系统模式中实施了一个基于过程的异戊二烯排放模型，并考虑了大气化学的耦合，以考察异戊二烯排放与气候之间的反馈关系。估计了工业化前(1860-1869)、现在(2000-2009年)和未来(2100-2109)气候条件下的异戊二烯排放及其对大气化学和气候的影响。目前全球异戊二烯排放总量的估计值为460 TGC/年，与以前的估计值一致。工业化前的异戊二烯排放量估计比现在高出26%。使用RCP8.5方案的未来异戊二烯排放与目前类似，因为气候变暖导致的排放增加被二氧化碳对异戊二烯排放的抑制所抵消。生物来源的异戊二烯排放对全球臭氧负荷和甲烷寿命的影响很小，但局部意义重大，异戊二烯排放变化对大气化学的影响强烈依赖于气候和化学状态。
[1] We have implemented a process-based isoprene emission model in the HadGEM2 Earth-system model with coupled atmospheric chemistry in order to examine the feedback between isoprene emission and climate. Isoprene emissions and their impact on atmospheric chemistry and climate are estimated for preindustrial (1860–1869), present-day (2000–2009), and future (2100–2109) climate conditions. The estimate of 460 TgC/yr for present-day global total isoprene emission is consistent with previous estimates. Preindustrial isoprene emissions are estimated to be 26% higher than present-day. Future isoprene emissions using the RCP8.5 scenario are similar to present-day because increased emissions resulting from climate warming are countered by CO2 inhibition of isoprene emissions. The impact of biogenic isoprene emissions on the global O3 burden and CH4 lifetime is small but locally significant, and the impact of changes in isoprene emissions on atmospheric chemistry depends strongly on the state of climate and chemistry.
