Summary: Regular data collection/cleaning, water level going down, installed radiometer intercomparison

2021-07-21
East End

Robert and I arrived at 12:05 PDT. It was a warm, hazy day. The reeds are looking tall and green, and the tules in front of the solar panel need to be trimmed before the winter (probably at WP as well). The water level is still going down and the staff gauge read 11cm.

I downloaded met, cam, and USB GHG data. We topped off the wash reservoir. Robert cleaned the flux and rad sensors.

We installed the intercomparison radiometers on the rad boom and leveled them. I connected to the comparison datalogger and confirmed the numbers looked reasonable.

Datalogger and sensors added:
CR1000 sn 23865
CNR4 sn 121038
PAR sn 060831
NDVI in sn 1049
NDVI out sn 1050

LI-7500 readings:
CO2 400ppm
H2O 760ppm
T 27.4C
P 101.1kPa
SS 98 --> forgot to write after cleaning
LI7700 readings:
CH4 2.0
RSSI 35 --> 80 after cleaning

We left at 13:05 PDT.
