Dear Isogeochemers,
I tried to know CO2 absorption effects of roadside trees by
del-13C and del-18O of CO2.
In my preliminary analysis, I found that del-18O of CO2 in urban air
(near road) were 7 to 20 permil (PDB base) in March in Japan.
But, I dont have any data set of del-18O of CO2 in air
Any information about del-18O of CO2would be greatly appreciated.
Thanks,
Dr. Kazushi TAKAHASHI
