| Zusammenfassung |
| A simple method for correcting NO2 emissions that employs an air quality model results and
satellite observations from OMI and SCIAMACHY will be presented.
A 3 year (2008-2010) air quality model simulation over Europe was undertaken. The
GEM-AQ model using EMEP emissions was run on a global variable resolution
grid centered over Europe with spacing of ~15 km (0.125ox 0.125o) in the core.
Monthly mean NO2 tropospheric columns were calculated using hourly model
results.
Monthly averaged NO2 tropospheric columns for the 2008-2010 were compared with
OMI and SCIAMACHY tropospheric products. This simple method based on differences
between model and satellite data allowed to define regions with systematic over and
underestimations of the modelled NO2 columns.
Results from this work allow for the development of emission correction factors that can
be applied to NO2 emissions fluxes for individual SNAP sectors. The GEM-AQ model
simulations were done for 2011 using adjusted emission fluxes. Monthly averaged
tropospheric columns were compared with available satellite products for 2011. |
