Field Notes

Bouldin Corn: 2019-06-04 12:35:00 (DOY 155)
Author: Robert Shortt
Others: Ariane Ortiz, Daphne Szutu

Summary: Corn in very early stages of growth (~5cm). Soil sensors put out into the field. Tower should be moved closer to field on next visit.

We arrived at 12:35pm. Weather was hot and sunny, with haze persisting on the horizon. The corn was in its very early stages of growth, with only the baby leaves grown so far. Tyler's chambers are back out in the field.

We put the soil heat flux and soil moisture sensors back out into the field, each at ~2cm. Daphne unplugged the Purple Air sensor, downloaded data, and plugged it back in, saw blue blinking light.

Saw that the tower's spectral boom was over weeds and is not representative of the field. Should be moved on next visit, but was too heavy for the three of us to shift on our own. Ariane cleaned sensors while Daphne downloaded data and Robert clipped weeds/refilled the wash reservoir (1/3 empty)

Weeds under BC tower radiometers; we need to move the tower closer into the field.
