We arrived at 13:55. The fields were dry but still soft. It was overcast and cool with a gentle breeze.

We swapped the 7500 (sn 0035 came down, sn 75H-2668 went up) and the 7700 (sn TG1-0211 came down, sn TG1-0155 went up). I collected met and camera data. Elke cleaned the rad and flux sensors. Kyle refilled the wash reservoir.

After we swapped the 7500, I uploaded a new configuration file and updated the pressure coefficients. After we swapped the 7700, I had to manually connect the sensor in the LI-7550 software. I changed the 7700 clock settings from slave to automatic. We confirmed the pump and spin wash worked, and then reset the LI-7550 box.

LI-7500 readings (sn 0035 --> sn 0035 cleaned --> sn 75H-2668)
CO2 405ppm --> 407 --> 409
H2O 477ppm --> 469 --> 467
T 17.7C --> ?? --> 17.9
P 101.2 kPa --> ?? --> 101.2
SS 98 --> 99 --> 101.6

LI7700 readings (sn TG1-0211 --> sn TG1-0211 cleaned --> sn TG1-0155):
CH4 1.91ppm --> 1.92 --> 1.94
RSSI 35 --> 67 --> 84

We left at 14:25.
