Summary: Standard fieldwork. Rice sooper droopy. All good.
| Twitchell Rice 2013-09-11 We arrived about 11:40 PDT. It was partly cloudy, breezy, and cool (19 C). The soil continues to dry out and the rice is super droopy with seed, about 65 cm high. I attended to the tower while Sara did spectral measurements and Dennis and Eva did clip plots. There may be a lower rice yield this year, Eva harvested quite a bit in her boots. 7500 readings: CO2 = 390 ppm (395 after cleaning) H2O = 690 mmol m-3 (675 after cleaning) signal strength = 85.7% (86.9% after cleaning) t = 22.7 C p = 101.9 kPa sos = 346.6 m s-1 7700 readings: CH4 = 1.87 ppm (same after cleaning) RSSI = 36% (73% after cleaning) Reservoir was full. MET data looked good. Cleaned radiation instruments. |
