Dear Sarah Fraser,

The link takes me to Cliflo. How do I get the station numbers to come up? Nothing seems to be showing. Or, are you not providing me with the data? Just a link to a subscription set up?

I was of the understanding that we can have access to meteorological data foc. Does that not happen any longer? If not, when did it change?

Thank you

T Dobbie
