Summary: Regular fieldwork. Swapped 7500. Installed LED sensor.
| Twitchell Rice 2014-06-26 We arrived about 14:15 PDT. Warm and sunny with a nice breeze. The rice is growing steadily. There remains a lot of visible weeds. I checked the tower, swapped the 7500 for a fresh one (removed sn 75H-2182, installed sn 75H-2150), and downloaded data. Sara took a veg height transect while Kathleen did clip plots. 7500 readings after swap: CO2 = 391 ppm H2O = 650 mmol m-3 signal strength = 92.6% p = 101.8 kPa t = 24.1 C sos: 348.2 m s-1 7700 readings: CH4 = 1.85 ppm (same after cleaning) RSSI = 54% (didn’t record % after cleaning) Met looked good. Joe met us at the site and added an LED sensor. |
