We arrived at 15:45. It was clear, sunny, and warm.

I started at the floor site. I downloaded the LicorGHG data, upgraded the LI-7550 sn AIU-1869 software from v8.5.0 to v8.7.5, and checked the site setup settings.

I swapped the LI-7500 head: sn 0042 came down, and sn 75H-2180 went up. I uploaded a new config file, updated the pressure coefficients, and reset the LI-7550 box.

Floor LI-7500 readings:
-First column is 7550 v8.5.0 with sn 0042, Second column is 7550 v8.7.5 with sn 0042, Third column is 7550 v8.7.5 with sn 75H-2180.

CO2 391.5 --> 394.8 --> 396.5
H2O 786.4 --> 788.4 --> 659.3
P 99.1 --> 99.1 --> 99.1
T 35.8 --> 35.6 --> 35.8
SS 100 --> 100 --> 101

Joe was at the tower site. He updated the CR23X met program to collect data every minute, which the datalogger can store for 12 days (if we collected data every 10 sec, the datalogger only had space for 2 days).

He downloaded the LicorGHG data and swapped the LI-7500 head: sn 0041 came down, and sn 75H-2182 went up. He upgraded the LI-7550 sn AIU-1866 software from v8.5.0 to v8.7.5, uploaded a new configuration file, and updated the pressure coefficients.

-First column is 7550 v8.5.0 with sn 0041, Second column is 7550 v8.7.5 with sn 0041, Third column is 7550 v8.7.5 with sn 75H-2182.

CO2 387.1 -> 387.6 -> 391.6
H2O 677.5 -> 678.4 -> 650.0
T 32.15 -> 32.21 -> 32.89
P 98.98 -> 98.99 -> 98.95
SS 96.1 -> 96.13 -> 88.3

We left at 16:30.
