About the data
Using satellite columns of HCHO retrieved from the GOME-2/MetOp-A sensor (De Smedt et al. 2012) over 2007-2012 as constraints in the IMAGESv2 chemistry-transport model (Stavrakou et al. 2014), we derive satellite-based estimates of fire emissions on a monthly basis. These emissions are available on monthly basis at 0.25° resolution.
The tables below showes the interannual variation for the OMI-based anthropogeninc emission estimates emssions 5 regions over china .
