Antarctic Clouds and Aerosols (ACA) Action Group

Terms of Reference

The Antarctic Clouds and Aerosols (ACA) Action Group was set up to have the following objectives -

1.    Encourage the development of a climatology of Cloud Microphysical properties over both the Antarctic Coastal area and over the Antarctic plateau. It hoped that this climatology will be the product of international cooperation, using ground based observation, in-situ measurements and satellite remote sensing.

2.    Identification of the sources of cloud nuclei that are important for the formation of Antarctic clouds.

3.    The development of new improved parameterisations of Antarctic clouds for inclusion within regional and climate models.
