Summary: Li-cor batteries low voltage; data downloaded and systems running properly.
| May 11, 2001 Liukang Xu Here is the note from my trip to the sites on May 11 d131. At Tonzi ranch: In the morning, A_Ci curve measurements, increasing the minimum and max waiting times to 7 min and 10 min. for each step and also the CO2 concentrations is from high to low, (1000, 700, 500, 360, 200, 150, 100, 50 ppm). in the Afternoon, only one A_PAR curve was taken due to the low battery voltage. We need another pack of Li-Cor 6400 battery, since voltage runs down much fast when I turn the cooling system on. around noon time, I download the flux data at both floor and tower systems. at Vaira ranch. around 5:00pm The grass was 95% of leaf turn yellow and dead, and heading fall off. Download the flux data, sonic system runs properly, and two datalogger and voltage reading are good. |
