There is a large square of ungrazed alfalfa where they fenced off the area between the tower and the rad boom. The soil respiration sensors and collars are in this area of ungrazed alfalfa. Downloaded data. Dennis and Housen did soil respiration. Ants in the met box – installed bait. 7500 readings: CO2 = 393 ppm (403 after cleaning) H2O = 608 mmol m-3 (560 after cleaning) signal strength = 87.2% (89.7% after cleaning) p = 102.3 kPa t = 21 C sos = 346 m s-1 |
