Bacteria in the ECHAM5-HAM global climate model

Bacteria are the most active naturally occuring ice nuclei (IN) due to the ice nucleationactive proteins on their surface, which serve as active sites for ice nucleation. Theirpotential impact on clouds and precipitation is not well known and needs to be inves-tigated. Bacteria as a new aerosol spec...
