I arrived about 12 noon with Dennis and Sam. It was clear, sunny and warm. There was about 90mm of rain last Friday through Sunday, but the ground surface looks dry and there was no puddles I could see. The trees still have leaves. The grasses and herbs have sprouted and the grass is maybe a cm high.

Dennis tested AirT and RH with a sling pyschrometer
Floor: Tdry 26.5 C, Twet 18.0 C â€“ calculated RH = 43.1%
Tower: Tdry 25.9 C, Twet 16.0 C â€“ calculated RH = 34.5%
HMP45 Floor: Tair 23.68 C, RH 34.2%
HMP45 Tower: Tair 22.3 C, RH 38.42%

I checked on the Tower top HMP45. I donâ€™t see any problems with it. We have some spare HMP60s in the lab. I think we will try an inter-comparison before we start swapping equipment.

There was a bunch of spider webs on the eddy sensors. I lowered the post to clean them off.

I cleaned the zcam windows but they were pretty clean considering the rain.
