Summary: Regular data collection/cleaning, uploaded LI-7550 master configuration file

Sherman Wetland

We arrived at 13:25. It was sunny and very windy, as usual. The rain gauge was completely clogged with blackberry seeds; Sam cleaned it out.

Elke refilled the wash reservoir; it was 4/5 full. Elke also cleaned the EC and radiation sensors.

I downloaded met, camera, and USB GHG data.

The Licor GHG data has been weirdly formatted, with extra columns of data and header/data don't quite match. There seems to be a problem with the LI-7550 configuration file.

I downloaded the complete configuration, "sn2667_1569_SW-all_20170913.l7x". I uploaded a master configuration file to the LI-7550, "AIU-0674_MASTER_20170912.l7x". The master file was saved in the lab using LI-7550 AIU-0674 and had all fields except for zero/span values and calibration coefficients. I reset the box. I checked the pressure coefficients matched and renamed the site/station name. The numbers look ok.

LI-7500 readings:
-First column is with original configuration file, second column is with master configuration file
CO2 386.8 --> 390.2
H2O 755 --> 728.1
T 22.1 --> 23.4
P 100.9 --> 101.3
SS 101 --> 106 after cleaning

LI7700 readings:
CH4: 1.93
RSSI: 48.0 -> 70.5 after cleaning

We left around 13:45.
