GEWEX Meetings

Cloud Assessment Workshops

Two workshops have been held in 2005 and 2006 in Madison, Wisconsin (USA), concentrating on the comparison of cloud amount.

At the third workshop, held in 2008 in New York (USA), for the first time cloud properties of twelve cloud data records have been directly compared. To facilitate assessments, climate studies, and evaluation of climate models, it was concluded to prepare a common database. Results have been presented at the fourth workshop in 2010 in Berlin (Germany). The presentations given at this meeting are available for download using the links below.
