Question: It would be interesting to evaluate MEGAN3 VOC emissions over extensive natural forests such as Boreal, Amazon and Equatorial African regions.
Answer: We agree completely that more evaluation of MEGAN3 is essential and
look forward to global model applications and additional observations that can provide such evaluation and, importantly, improve the MEGAN3 input databases and
then share the improvements with the modeling community. A primary motivation
for developing the MEGAN3 emission factor preprocessor (EFP) is to encourage
community-wide contributions that improve MEGAN3 for everyone.
