This morning the temp rose from -6.2 at 0800 to -0.8 at 0900, then to 1.2 at
0930.
My Davis was in bright sushine, but is a rise of 7.4c in 90 minutes really
correct?
I also believe that it over-cooks the temp a bit as well at times. I'd been
interested to hear any comments.
Part 2 to follow.

Perfectly possible, David. The strong, nocturnal inversion no doubt eased
off rather quickly with the strong insolation. Did you notice a wind speed
increase at some stage as the boundary layer "recoupled" ?

Blimey Joe, that was a quick response. The breeze kicked in at 0850.

I watch this newsgroup like a hawk. Yes, I jest.

It was noticeable here too this morning with an 8degC rise in temperature
within two hours.

I know my Davis ISS is in the shade from the house for the first few
hours, this morning rose from -5.0 at 07:00 to -1.1 at 09:00. Graphs on
the site in the sig.

I'll try to remember to observe tomorrow what sort of time the ISS gets
direct sun, see if this correlates with a small step change of about
0.5C about 10:00.

(The solar radiation sensor is remotely mounted above the roof ridge to
get an unobstructed view of the horizon from NE-S-NW)
