Summary: Swapped 7500 for calibration, water level still rising

2020-12-09
Sherman Wetland

Joe and I arrived at 14:20 PST. It was a sunny day with stratus clouds and hazy horizons. The water level is still climbing; the staff gauge read 94cm.

We swapped the 7500 for calibration: sn 75H-2667 came off and sn 0065 went on. I uploaded a new config file, updated pressure coefficients, and reset the box. I downloaded met, camera, and USB GHG data. Joe cleaned flux and rad sensors. There were a few ants crawling about so I left some mothballs in the met box to deter more ants.

LI-7500 readings (sn 75H-2667--> sn 0065):
CO2 428ppm --> 440
H2O 297ppm --> 282
T 19.6C --> 20.8
P 101.6kPa --> 101.5
SS 102--> 100

LI7700 readings:
CH4 2.3ppm
RSSI 50-->79 after cleaning

We left at 14:35 PST.

Looking at data back in the lab, most of the photos from the past week were missing. Maybe it's time to swap out the card.
