Intercomparison and evaluation of aerosol microphysical properties among AeroCom global models of a range of complexity

This study examines the global variation in particle size distribution simulated by twelve global aerosol microphysics models to quantify model diversity and to identify any common biases against observations. Evaluation against size distribution measurements from a new European network of aerosol supersites shows that the mean model agrees quite well with the observations at many sites on the annual mean, but there are some seasonal biases common to many sites. TNO contributed to this study with aerosol observations from supersite Cabauw.
