Aerosol size-dependent below-cloud scavenging by rain and snow in the ECHAM5-HAM
size-dependent below-cloud scavenging rain snow ECHAM5-HAM
2009/7/23
Wet deposition processes are highly efficient in the removal of aerosols from the atmosphere, and thus strongly influence global aerosol concentrations, and clouds, and their respective radiative forc...
Identifying convective transport of carbon monoxide by comparing remotely sensed observations from TES with cloud modeling simulations
Identifying convective transport carbon monoxide TES
2009/7/15
Understanding the mechanisms that transport pollutants from the surface to the free atmosphere is important for determining the atmosphere's chemical composition. This study quantifies the vertical tr...

2009/7/1
A daytime climatological spatio-temporal distribution of high opaque ice cloud (HOIC) classes over the Indian subcontinent (0–40° N, 60° E–100° E) is presented using 25-year data from the Advanced Ver...
The relationship between aerosol and cloud drop number concentrations in a global aerosol microphysics model
aerosol cloud drop number concentrations global aerosol microphysics model
2009/6/23
Empirical relationships that link cloud droplet number (CDN) to aerosol number or mass are commonly used to calculate global fields of CDN for climate forcing assessments. In this work we use a sectio...
