Description

During the preparation of the last TRENDY simulation, we were contacted by a former postdoc (Xiuzhi Chen) to provide respiration per plant compartment. I made the required modification and Vlad made the simulations. The Chinese team recently sent a draft where the ORCHIDEE soil carbon stocks were anomalously low.
Vlad has created the following page using the available reference simulations, where you can see that the drop (more than 30%) occurred between r3429 and r3525:
