Twitchell Alfalfa: 2016-07-06 13:50:00 (DOY 188)
Author: Alison Haddad
Others: Elke Eichelmann, Kyle Hemes

Summary: Alfalfa cut recently, no veg height or spectral measurements, normal data collection.

Arrived 13:50. Clear, sunny, warm, breezy. Alfalfa cut recently.

Collected USB GHG data, collected canon camera data, collected met data: STC12 and STC14=NAN, collected rad data from CR10X: collected camera SD: swapped CF card “SI” in and “TA2” out, collected soil CO2.

Did soil respiration measurements, cleaned solar panels, cut alfalfa around met equipment.

Did not take vegetation height measurements or clip plots because alfalfa was recently cut.

Could not take spectral because the sensor kept reading “too much light” during the reference measurement.
