Summary: Trees beginning to leaf out, replaced second from bottom hmp45 fan, fixed tower fence and tram fence, swapped pyranometer desiccant.

I arrived about 11:00 with Siyan. It was partly cloudy and mild with gusty wind from the south west. The grass looks green and happy with some flowers beginning. A few of the trees are beginning to put on leaves.

I collected data, serviced the zcams and calibrated the CO2 profile system.

I cleaned the radiometers and swapped the desiccant in the pyranometer. The BF5 had almost no condensation, but we should swap its desiccant again next time.

The ventilation fan on the HMP45 second from bottom (1.3m) was dead. I swapped it out.

One trunk of a dead tree just north of the tram has broken about 10ft up and fallen over the cow fence. It has not touched the fence and still seems securely connected to the tree. But, it might completely fall and damage the fence later. Some smaller dead branches fell on the fence in the south west corner. I cleaned those up and fixed the fence.

A dead branch also fell on the soil CO2 battery boxes. They are okay for now but should probably be checked later.

I fixed a broken wire on the main tower fence.
