Welcome to the firstDOE/EU Ground-based Cloud and Precipitation

Retrieval Workshop

University of Cologne, 13.-14. May 2013

on behalf of Wanda Ferrell (DOE)

Susanne Crewell (University of Cologne)

Advance algorithm development and uncertainty quantification for retrieving cloud and precipitation

properties from ground-based remote sensors through international scientific collaboration and data sharing.

Organizers:Jennifer Comstock

Kerstin EbellUlrich LöhnertDave Turner

Workshop objective

Possible outcomes

• Identify common algorithm frameworks and paths forward for improving and/or implementing retrieval algorithms across EU and ARM observing stations.

• Identify common algorithm evaluation approaches that will be used for algorithm development and uncertainty quantification.

• Identify geophysical variables that can be commonly retrieved and shared across the EU and ARM observing stations through a common data portal.

• Create a common information exchange platform?

What do we specifically need to propose to ARM/DOE or EU agencies to improve existing algorithms?
