Bouldin Alfalfa: 2025-06-11 10:50:00 (DOY 162)
Author: Carlos Wang
Others: Dennis, Joy

Summary: regular data download and maintenance | phemocam clock sync | sonic heading measurement (250 deg N)

Dennis, Joy, and I arrived at Bouldin alfalfa gate at ~1030, but the gate had a new lock added. A truck driver was leaving as we got there, so we were able to get in. We also got the new lock code. We arrived at the field at ~1050, it was hanzy, windy, and warm. The field, though still bare, had been plowed with ditches dug.

At the tower, I collected the MET, flux, LI-720 and camera data.

Dennis and Joy cleaned the MET and flux sensors. The radiatometer was quite dirty. I reset the flux clock, which was ~1 min behind. Afterwards, I restarted the logging.

7500 read: 403ppm CO2, 634mmol/m3 H2O, 22.2 C, 101kPa, 95SS --98

I checked th phenocam clock and synced time. Dennis measured the sonic heading: 250 deg N True.

We left the field at ~1130 and went to Twitchell Island.

Estimated Next Mowing: 2025-06-08
