OLCI PPE filtering and C2RCC

I have tried to use the ‘OLCI PPE filtering’ operator prior the ‘C2RCC’ operator, applied to OLCI L1b data.
When using the output of the ‘OLCI PPE filtering’ as input in the ‘C2RCC’ operator, I got the following error message:

A problem occurred during the target product initialisation.
Type: OperatorException
Message: Could not retrieve time information from source product

From the PPE filtering paper, I see that the PPE filtering is mostly useful when processing data in the area of South Atlantic (Magnetic) Anomaly (SAA). I am wondering if the OLCI PPE filtering is recommended also for other geographic areas. Any of you has experience on this issue?

Regards,

Federico

Thanks for the report Federico. Indeed it was forgotten to copy the time information to the output of the PPE operator. To workaround for testing, you can manually add the time information in the properties dialog of the product.

A fix will be released with the next update.
