Summary: Swapped out 7500 for calibrated one. Cleaned rain funnel of bird poop.
| Wetland Construction 2013-08-21 We arrived around 10:00 PDT. It was sunny, cool (18 C), and super windy. The footprint continues to be overgrown. We swapped out the 7500 (sn 0976 box and head) with a calibrated one (sn 0042). 7500 readings (before swap): CO2 = 15.66 mmol m-3 (16.5 after cleaning) H2O = 750 mmol m-3 (620 after cleaning) Diag: 249 (same after cleaning) t = 21.95 C p = 101.0 kPa sos = 343.5 m s-1 7500 readings (after swap): CO2 = 16.3 mmol m-3 H2O = 640 mmol m-3 Diag: 248 t = 20.7 C p = 101.3 kPa sos = 343.5 m s-1 MET looked good. Joe noticed that there was bird poop blocking the rain funnel. He cleaned it out and in the process tipped the bucket a few times (delete this data). Laurie noted that the radiation sensors are over tall vegetation, which is partially indicative of the footprint. Cleaned solar panels. |
