Summary: Water levels higher. Raised forerunner. Swapped IRGA.
| East End Wetland 2014-09-25 We arrived around 12:40 PDT. It was partly cloudy, warm, and nearly calm. The water levels are higher and cattails continue to fill in and grow. Sara raised the forerunner CO2 probe from about 20-30 cm below the surface to about 5 cm below the surface. (Note 2020-09-28 Daphne - water level sensor also probably moved.) She reported it was thriving with critters – she cleaned it. Dennis cleaned the radiometers, they were dirty. We swapped the IRGA (removed sn 0041, installed sn 0073). Readings after swap: CO2 = 16.2 mmol m-3 H2O = 630 mmol m-3 p = 101.5 kPa t = 22.8 C diag: 249 CH4: 1.95 ppm RSSI: 67% Met looked good. |
