Radiosondes developed at CAIR will be provided for cloud and aerosol measurements on the Antarctic Peninsula carried out in collaboration with the University of Santiago, Chile. The goals are to:
• Measure low-cloud properties in situ over the Antarctic Peninsula, Southern Ocean, and West Antarctic Ice Sheet.
• Validate satellite-based measurements and compare results with reanalysis data and surface-based measurements made elsewhere in Antarctica.
• Investigate the influence of sea ice concentration on cloudiness in the Southern Ocean, using these measurements and satellite-based measurements.
• Validate and improve the representation of clouds and radiation in forecast modelling.

Layman's description

Unique balloon-borne radiosondes capable of measuring the size of cloud and aerosol particles will be used to determine the contribution of clouds to the rapid warming currently happening in the Antarctic.
