Emission inventory

Satellite-derived anthropogenic VOC emission estimates based on OMI HCHO observations (2005-2014)


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.



These emissions are here available in NetCDF format in 0.25x0.25° resolution over the Asian continent



Additional information

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.





The development of this dataset was made possible by the support of the European Space Agency (ESA) through the GlobEmission project (2011-2016): Visit the web portal of the GlobEmission project for more information.
