were is the best place for the weather station now i have got the weather station on treliceing

Do you mean trellising ?

... and why is it there ?

For all of us positioning is a 'local environment' thing.

Lots of posts on what people have done / experimenting with - even a couple that give you unachievable / not underderstable guidelines from met offices various.

First thing to understand is that all your kit shouldn't be in one cluster (that includes Davis)

Wind gear, 30 feet / 10m up in the clear or at least 4m above your roof / local obstructions/
Thermohygro - approx 5 feet / 1.5m above grass, in the shade ('old' head height)
Rain-bucket - approx 20 inches / 500mm above ground level to avoid splatter and wind shear, also reasonably shaded by wind.

This is why we 'play' with the kit we have

thank you for that i will have a go at that

For some of ours, siting a Weather Station in a urban environment maybe a nightmare...

John Dann also has some excellent advice on siting sensors: http://weatherstations.co.uk/gooddata.htm

Here's what I've done, its not perfect but the results have shown its not a bad compromise. (its a big image so I'll leave it as a link)
