Methodology• Gathering of one year model data in netcdf format, daily
on AeroCom server– BSC-DREAM8b– ECMWF-F026 (assimilating MODISaqua/terra) plus other versions– INCA-forecast plus other versions– NMMB-BSC
• Analysing daily fields of AOD, coarse mode AOD,emission, wet removal, load, surface concentration of dust
• Comparing to Aeronet data level 2, sun and sky mode– ( Total AOD@550 )– Coarse mode AOD@550

Proposition for joint studyto explore usage of coarse AOD for evaluation
Complete and check diagnostics, newer model versions? Retrieve size from all tracer 3D field…
Correct budget analysis and analyse dust life time Use non-assimilated ECMWF model version
for comparison of impact of assimilation Explore the contribution of other components to coarse AOD,
remove cases which are not dust dominated
Investigate on annual basis: which cases are well captured, which pose problems
Add more models ?? Other years ??
