Summary: Regular data collection, swapped LI7500, field drained

We got out here at 9:10am, sunny, clear skies. There were lots of geese in the fields driving up to rice (but none in the rice field). The field was drained, but still very muddy.
The computer battery was dead, so we had to leave and buy a charger. Got back to the field around 10:00am.
Collected met data, collected USB GHG data. No camera installed here.
Swapped the LI7500. Took down sn 75H-2182, replaced with sn 75H-2176.
LI7500 readings before the swap: CO2: 431.5, H2O: 550.3, SS: 83.91, T: 15.25, P: 102.9
LI7500 readings after the swap: CO2: 435.4, H2O: 515.0, SS: 88.4, T: 15.56, P: 102.5
LI7700: CH4: 2.215; RSSI: 45.2 -> 73.45 after cleaning.
Soil HFP2 recording small negative numbers while all others show large positive numbers, probably bad.
After the swap updated LI7500 config settings for calibration. Also updated settings for LI7700 to reconnect to Licor datalogger.
