| Twitchell Alfalfa 2014-04-03 We arrived about 13:40 PDT. It was cloudy, cool, with a light breeze. Alfalfa growing steadily. I checked the readings while Patty did spectral and clip plots. After I did LAI 2000 measurements and measured veg height. All looked good except the soil heat flux measurements which were all giving zero this week. 7500 readings: CO2 = 393 ppm H2O = 425 mmol m-3 SS = 93.29 sos = 344.0 m s-1 t 17.31 C p 101.84 kPa |
