Summary: Took vegetation height and biomass samples. Problems with NR1 PRT temperature.
| Arrived at 12:00. The weather was sunny, clear and windy. Collected USB CAM MET. Looked at 7700 pressure. Cleaned radiation and eddy sensors. Measured tower height from the ground. 5.11 m from the middle of the 7700. 4.88 m from the bottom of the 7700. Ch4 1.20 to 2.9 Rssi 1.1 to 77.3 Ch4 press = 41 CO2 398.11 to 405.6 H2o 635.9 to 575.0 T 31.04 P 101.1 Ss 83.0 to 86.1 NR01 PRT started nan June 19 1:30 Changed excitation from vx2 to vx3 and updated program but still nan Maybe resistors? In program, Daphne switched channels of AMS25T and NR01PRT. Took vegetation height and biomass samples. Vegetation Height (cm) Walking out: 45, 40, 35, 22, 17, 13, 25, 35, 28, 31 Walking back: 37, 26, 32, 29, 28, 36, 24, 38, 40, 23 Biomass Samples (counted plants within 1m of a row, took samples from the first 50cm for every second site) Site 1: 9 plants—no sample Site 2: 6 plants—3 plants (I) Site 3: 8 plants—no sample Site 4: 9 plants—5 plants (II) Site 5: 8 plants—no sample Site 6: 7 plants—4 plants (III) Site 7: 8 plants—no sample Site 8: 8 plants—4 plants (IV) Site 9: 8 plants—no sample Site 10: 8 plants—4 plants (V) Need to find out row spacing! |
Veg Height (cm): Tape measure from ground to top of plant
45, 40, 35, 22, 17, 13, 25, 35, 28, 31, 37, 26, 32, 29, 28, 23, 21, 28, 20, 25, avg = 28, stdev = 7.88
