Work on the paper is coming along slowly. I just need contributions from Keith and Tim here and Caspar at NCAR. I'm away July 16-28, so I hope that the final contributions will arrive whilst I'm away, just like Swiss trains - always on time! I've reminded Keith and Tim, so remember Swiss timing Caspar!
