Zhuanshi Thanks for that! I've never seen that website before and it looks really useful! I think those functions look a lot more straight forward than any of the others I've seen today in my searching.
I'll let you know if I get it sorted! Jenny > >Hi Jenny, > >Maybe the following links will be useful for you. Both of thoes are >used in meteorological and climate research community.
