Summary: Standard fieldwork, replaced fans in HMP45 profile.

Tonzi
2015-02-04

I arrived about 11:00 with Siyan, Housen and Ana. The Delta and Central Valley had heavy fog, but here it is mostly clear and sunny with little to no wind. Tonziâ€™s pond is still only about half full, but the grass looks okay. I saw several pine seedlings.

Housen and Ana saw the site and Siyan did the standard fieldwork. I collected data.

I replaced the fans in the HMP45 solar shields in the bottom and 6m locations.

The Tower sonic box had locked up again. I will replace it with a RS232 to 422 converter next time.

I forgot to bring the desiccant for the BF5 and pyranometer.

I calibrated the CO2 profile sytem.
