CREW 3
From 15.-17. November 2011 the Third Cloud Retrieval Evaluation Workshop (CREW 3) will be hald in Madison, USA. The Workshop is hosted by the University of Madison and sponsored by Eumetsat. We invite experts working with operational cloud parameter retrieval schemes from passive imagers (SEVIRI, AVHRR, and MODIS), passive microwave (AMSR), and active liders and radars (CPR, CALIOP) to participate in the workshop and to contribute to the cloud parameter inter-comparison and validation campaign in connection to the workshop.
Registration: Deadline for abstracts: 31-03-2011

CREW 2
The second Cloud Retrieval Evaluation Workshop took plave in Locarno, Switzerland from 03.-05. Februar 2009.
CREW 2 went a step further than the first workshop. Additionally to the intercomparison of SEVIRI algorithms, cloud parameters were also compared to data sets of the ATRAIN satellites CPR on CLOUDSAT, CALIPSO on CALIOP as well as MODIS and AMSR-E. CLOUDSAT is a satellite-based radar that provides a vertical view into clouds along its path. It is well suited to compare cloud top heights. CALIPSO, as a lidar sensor, is more likely to detect also thin cirrus clouds. AMSR-E is a microwave sensor and is used to compare the liquid water path over ocean from measurements in a different spectral region. MODIS has similar channel settings as SEVIRI and has a wide range of atmospheric products. In this way we gained more knowledge on the behavior of the different retrieval schemes for different cloud conditions.

CREW 1
The first Cloud Retrieval Evaluation Workshop took plave in Norrköping, Sweden from 17.-19. Mai 2006. CREW 1 gave a good overview on the availeble retrieval schemes, their applications and their differences. The idea was to present the output of the algorihms not only in individual presentations, but also to have an independent and objective inter-comparison of the data. For this purpose all participants provided the resuts of their algorithms for one observation day. The analysis for this first workshop was limited to inter-comparison of SEVIRI algorithms.
