Summary: Regular data collection/cleaning, wetland still green, tested tipping bucket--no adjustment needed

2019-11-19
Sherman Wetland

I arrived at 9:30 after dropping Ariane off at MB for water sampling. It was a clear, windy day, with some low cumulus clouds to the south over the hills. The water level was 87 cm. The wetland is still mostly green.

I collected met, USB GHG, camera, and miniDOT data. The NDVI_out sensors were NAN; a power cycle seemed to resolve the problem. I swapped the minidot desiccant. The wash reservoir was 2/3 full; I refilled it. I cleaned flux and rad sensors. The top rectangular sensor window on the Arable was a bit muddy.

I tested the tipping bucket sn 65552-615. The funnel looked clean (surprisingly), so I connected it to a CR23x and dripped 475ml of water through the bucket, which should result in 100tips--got 100 tips exactly, so I did not adjust. The bad reading last time must have been the result of spiderwebs in the tipper that Joe had cleaned out.

LI-7500 readings:
CO2 323ppm
H2O 219ppm
T 16.7C
P 100.8kPa
SS 60 --> 98
LI7700 readings:
CH4 2.03 ppm
RSSI 47--> 85 after cleaning

I left at 10:20.
