Tom,

Sorry to take too long to respond. As you can see from previous messages, we've had a serious post-processing bottleneck with RUC-2 because of the need to do this on a computer that isn't very efficient for it. So, no, the cloud variables will be available only in the native grid for the time being. But the isobaric supplemental files were themselves half the size of the native files. What is your comms set-up like? Can you download somthe native files on a lower-frequency basis to use?
