Summary: Regular data collection/cleaning, swapped in brand new AM16/32 mux, water samples for Isabel, serviced water sensors

We arrived at 9:55. It was cool and overcast with a light breeze. The wetland is brown and dead.

We refilled the wash reservoir; it was mostly full. Alex collected water samples for Isabel at 10:00.

The camera was off and there was only one photo: last time we swapped the power cable, which cut the camera power, and then forgot to turn on the camera again. Alex cleaned the EC and rad sensors.

I downloaded met, camera, and USB GHG data. There were spikes in SWout; PAR had occasional NANs, and NDVI_in was reading NAN. Since we've had trouble with the radiometers with the past two mux, I swapped in a brand new AM16/32 mux: sn 1236 came off, sn 26950 went up. I consolidated the sensors on lower channels, and updated the program so that it had the correct channels. The new met CR1000 program is MB_met_20180229.CR1.

I tried to connect to NDVI_in sensor through the Terminal Emulator, but â€œSDI Failed.â€ I power-cycled the NDVI sensors, and both NDVI sensors worked again.

Elke collected miniDOT data and cleaned all the water sensors. The miniDOTs will need new sn stickers soon.

LI-7500 readings:

T 9.7C
P 102.1 kPa
SS 101 --> 101 after cleaning

LI7700 readings:

RSSI 54 --> 74 after cleaning

We left at 11:10.
