Gound-based in-situ
  • Representativeness of European key sites
     
  • Presentation given by S. Henne at EGU general assembly, Vienna, 2008.

 
 
Composite of total annual surface footprints (500 m) for selected sites calculated with COSMO LPDM and FLEXPART after 48 hours of backward integration. Purple to blue colours indicate small and red colours high residence times.

Ground-based remote sensing
  • Satellite validation of NO2
     

 
 
First results of satellite validation of tropospheric NO2 by BIRA-IASB. Ground-based MAX-DOAS data interpolated at the time of the satellite overpass (closest point of cloud free data within 50km for OMI)).
