Also just as a quick sidenote you will either get a 9 hour or 18 hour TAF for an airport. Most major airports will have both (Gatwick and Manchester for example), some smaller airports only release a 9 hour forecast (like Leeds-Bradford).

The format you see above is used for TAFs in practically the whole world, except the USA and Canada who use a slightly different system for reasons best known to themselves.

In the USA if the cloud layer is broken or overcast, it will be in "above Aerodrome Level". If the cloud layer is few or scattered, it will be in mean sea level.

Are you sure? I looked through my NAAQ notes for North American Airspace and it does not mention this very important difference between US and International TAFs / METARs?

There is a significant section on the differences between International and US / Canada coded observations and forecasts, but the cloud cover section is listed as "identical format".

This would suggest FEW / SCT / BKN / OVC with the last three digits indicating the height of the base of the cloud in hundreds of feet above aerodrome level, even in the US format.

Must bring this difference to the attention of the training department if this is wrong, as I have always assumed it was as above.

Could you let me know where I could find this info? Thanks.
