Aerosol, Cloud, Precipitation and Radiation Studies over High Latitude Oceans
Session ID#: 156802
Session Description:
Uncertainties in numerical weather and climate prediction in Earth system models over high latitudes (i.e., the Arctic and Southern Ocean) are associated with large biases in the simulated radiation budget and large uncertainties in earth system feedback processes, such as the simulated Arctic sea ice response to warming. Improving deficiencies in high latitude earth system modeling has been limited by a lack of in situ and remote sensing observations needed to adequately constrain the representation of aerosol-cloud-precipitation-radiation interactions in numerical models. Several recent observational campaigns over the Arctic and Southern Ocean have been dedicated to improving fundamental understanding of microphysical processes occurring in liquid and ice-containing clouds, and determining roles of primary and secondary marine biogenic aerosol particles and sea-salt emissions. This session welcomes contributions that 1) describe recent ship, ground or airborne measurements of high latitude aerosol, clouds, precipitation, and radiation, 2) use data from such campaigns, satellite remote sensing, and/or 3) use numerical simulations any spatial/temporal scale to advance the understanding of aerosol, cloud, precipitation and radiation properties and their interactions.
