Which One Should I Trust?

[Backtrack]

Hi all. I have 2 weather stations. One which is situated on my garden gate - It's currently reading 11.1c. I have another weather station which was more expensive - Has a stevenson screen ect - But is 3 ft above a non working chimney. This is reading 11.9c. What do I trust?

11.9c seems better. On Xc weather stations around you are more at 12/13c.

I thought that too, but Liverpool is normally much warmer than us. Hawarden is a frost hollow, and Manchester is too far away to make a judgement.

what height above the ground are they?

I think 1.2m above ground is best.

Can anyone check for me ? My readings are

Temperature 10.1C Humidty 70%

Dew Point 5C

Seems close enough. Dew point perhaps more likely to be 6c according to xc weather but local variations will apply.

Sensor 1 = 1.2m

Sensor 2 = 25ft?

If it's fairly clear, your lower one is acting somewhat like a ground temperature measure -

sometimes higher, but in this sort of weather being near the ground the nearby objects lose heat fast.

It's like how cars will sometimes have frost on them when it's a degree or two above freezing.

Thank you very much 4wd. Makes sense also, as my back garden is really enclosed!

I'll trust the higher one then from now on.
