The figure below illustrates anthropogenic VOC emission estimates in 2008 obtained from the REASv2 inventory and from the OMI-based product (units are in TgC/yr)

About the data
Using global satellite columns of HCHO retrieved from the OMI sensor (De Smedt et al. 2015) over 2005-2014 as constraints in the IMAGESv2 chemistry-transport model (cf. Stavrakou et al. 2015, 2014 for details on the model), we derive satellite-based estimates of pyrogenic VOC emissions on a monthly basis.
The tables below illustrates the interannual variation for the OMI-based anthropogeninc emission estimates emssions 5 regions over China and the national emission estimates for 7 Asian countries.
