About the data

The top-down emissions are inferred from an inverse modelling scheme based on the MAGRITTE regional model (Müller et al., 2019, Stavrakou et al., 2016) and are constrained by HCHO column observation from the QA4ECV product from the OMI sensor (De Smedt et al., 2018). The a priori emission inventory used in MAGRITTE is based on the MEGAN-MOHYCAN emission model and described in Stavrakou et al. (2018).

Formaldehyde is formed during the oxidation of most VOCs released in the atmosphere.  HCHO is a high yield product formed the oxidation of isoprene and the current chemical mechanism of MAGRITTEv1.1 is described in Müller et al. (2019). The data are provided in the frame of the scientific data exploitation SOLFEO project (Spaceborne Observations over Latin America For Emission Optimization applications, 2019-2020) supported by the European Space Agency.


Monthly emissions are available in NetCDF format at a resolution of 0.5°x0.5°.
