Description

The online calculation of mineral dust emissions involves a mapping of the size distribution obtained using the sectional model of Tegen et al. (JGR, 2002) onto the log-normal accumulation and coarse modes of M7. This part of the calculation has been modified, resulting in two to three times higher emissions in the accumulation mode. For details, see the new comments in the code.

The attached figures show the impacts on the simulated annual mean dust load, aerosol optical depth (AOD) and contribution from mineral dust, as well as a comparison of the simulated annual mean, summer (JJA) and winter (DJF) AOD field with correction for stratospheric aerosols included with MODIS.
