Summary: Swapped 7500. Data download. Swapped FR probes.
| West Pond 2015-01-20 Patty and I arrived around 11:50 PST. Joe was still working at EE. The sun started to come out and it was somewhat warmer. Water levels seemed ok. We downloaded data and swapped the LI-7500 for calibration (sn 75H-2180 came off and sn 75H-2182 went on). We also swapped the forerunner probe and installed one with new copper mesh at the bottom (sn GP20140021 came off and sn GP20140022 came on). Patty wrapped the connector with silicon tape. Readings: CO2 = 430 ppm before swap (431 after swap) H2O = 501 mmol m-3 before swap (521 after swap) signal strength = 92% before swap (85 after swap) p = 101.7 kPa t = 11 C sos = 341.9 m s-1 CH4 = 2.3 ppm RSSI = 22% (78% after cleaning) Reservoir was close to empty, refilled. Met looked good. |
