Abstract

BVOC forest soil emission rate decreased by 43% under long term amplified drought (after 10 years of summer rain exclusion).

• Forest soil respiration was a strong driver of soil BVOC emissions.

• Temperature was positively correlated to forest soil BVOC emissions following Tingey's model. • Forest soil BVOC followed a diurnal pattern with maximum emissions during central hours of the day.

• Forest soil was mainly a source of BVOC but it was a sink of isoprene.
