Summary: Regular data collection, spectral, measured height of flux sensors.

2018-08-07

We arrived at 13:56.

The weather was mild, very windy, and the sky was still covered in a dense layer of ash and smoke.

Daphne did regular USB, met, and cam data collection. Daphne also checked the phenocam text overlay and found that even when changing settings, the pictures still said "Twitchell Alfalfa". She power cycled and will have to investigate further to see if this fixed the issue.

Dennis did spectral (run in reflectance mode), taking a reference and zero, repeated down and up measurements, a dark reference, more samples, and another dark reference. The first set of measurements may be off scale. Vegetation was mostly dry.

Was reservoir was mostly full.

Robert cleaned rad and flux sensors. Height from middle of sonic to ground was 310 cm.

We left at 14:27.
