| Twitchell Alfalfa 2014-06-26 We arrived about 15:00 PDT. It was hot and sunny with a nice breeze. Sara and Kathleen did a veg height transect while I attended to the tower and downloaded data. We need to bring the large shears next time to cut down the tall grass around the tower. 7500 readings: CO2 = 385 ppm (395 after cleaning) H2O = 700 mmol m-3 (600 after cleaning) signal strength = 93.4% (94.4% after cleaning) p = 101.3 kPa t = 26.6 C sos = 348.9 m s-1 Met ok. Rad ok. |
