aerosol-cloud-precipitation stratiform orographic mixed-phase clouds
2010/9/14
This study presents results from a model intercomparison of 2-D simulations of aerosol-cloud-precipitation interactions in stratiform orographic mixed-phase clouds. The sensitivity of orographic preci...
Technical Note: Vapor pressure estimation methods applied to secondary organic aerosol constituents from α-pinene oxidation: an intercomparison study
Vapor pressure estimation methods secondary organic aerosol constituents α-pinene oxidation
2010/8/16
We applied and compared seven vapor pressure estimation methods to the condensable compounds generated in the oxidation of α-pinene, as described by the state-of-the-art mechanism of the BOREAM model ...
Intercomparison methods for satellite measurements of atmospheric composition: application to tropospheric ozone from TES and OMI
satellite measurements atmospheric composition tropospheric ozone TES OMI
