Twitchell Alfalfa 2014-05-29 We arrived about 14:15 PDT. It was hot and sunny with a nice breeze. The ditch we drive in to the tower in was wet. The alfalfa is fully flowered. I attended to the tower while Dennis, Sara, and Kathleen took clip plots, spectral and LAI measurements. Madeline took a veg height transect. Reinstalled multiplexor AM25T sn 6767, transferring all TCs over from temporary mux AM16/32 sn 1164. Uploaded new program. All readings good. 7500 readings: CO2 = 392 ppm (398 after cleaning) H2O = 700 mmol m-3 (660 after cleaning) signal strength = 93.7% (94.3% after cleaning) p = 100.7 kPa t = 31 C sos = 352 m s-1 Met ok. Washed solar panels.
