Results from the inter-comparison

The first workshop CREW-1 concentrated on the inter-comparion of SEVIRI algorithms

Cloud mask of 3 retrieval algorithms

Up to now a detailed analysis was done for cloud mask and cloud top height. In future a detailed analysis of all available parameters is planed.

Validation against A-Train observations

Following diagram shows the comparison of the cloud top height. The mean of the cloud top heights of several retrieval schemas from SEVIRI is shown in black, the measurement of CALIOP in green and CPR in red.

Validation of the Cloud top height with A-train measurements

Calculation of meaningful Level 3 product

In the third workshop CREW3 in November 2011, another field of investigation is added to the present fields of investigations. We will analyse how to calculate temporal averages of cloud properties (daily and monthly). The effects of different level 2 datasets and of different level 2 to level 3 algorithms will be investigated. In addition the propagation of the uncertainty will be analysed.
