Summary: Switched 12V power wire for water level, normal data collection, lots of weeds.
| Arrived: 9:20. Sunny, clear, light wind, hazy in the distance. Lots of weeds in the field, almost no rice in front third of the field. Methane wash water reservoir already full. Collected USB GHG data; collected met data from 23X, SHF1=-INF, all else looks good; did not collect camera card images. Collected 5 biomass samples, and vegetation height measurements Veg height (cm): 69, 70, 65, 69, 83, 77, 75, 73, 80, 77, 80, 89, 79, 74, 72, 70, 70, 74, 73, 75. Cleaned solar panels. Measured water level around tower (cm): 16, 11, 8, 15, 18. Switched 12V power for water level from one shared with AM25T to one shared with pressure sensor, net radiometer, and some other stuff. LI7500 readings CO2 398.36 H2O 653.0 T 19.03 P 101.72 ss 82.93 -> 83.5 after cleaning LI7700 readings CH4 1.90 -> 1.93 after cleaning rssi 52 ->69.7 after cleaning Left: 10:05 |
