Summary: Regular data collection/cleaning, swapped 7500
| 2017-03-15 Twitchell Rice We arrived at 11:35. It was partially overcast and cool with a light breeze. The rice field is drained but still muddy. There are ants in the datalogger box so we put in fresh moth balls. The wash reservoir was almost full and we topped it off. We swapped Li-7500: sn 75H-2182 came down and sn 75H-2150 went up. We uploaded the new config file and updated the pressure coefficients. We cleaned the EC and radiation sensors and collected the USB GHG, met, and camera data. The new camera card moves the photos to the laptop faster than the previous card. LI7500 readings: CO2 419.76 umol/mol --> 418.01 after swap H2O 602.5 mmol/m3 --> 659.2 after swap (seems high?) T 19.1 Celsius --> 19.7 after swap P 102.3 kPa --> 102.3 after swap SS 83.8 -> 96.5 after swap LI7700 readings: CH4: 1.98 RSSI: 38.7 -> 69.5 after cleaning We left at 12:10. |
