| 2009-04-03 | 4993 | CFM100 | Installed | Installed with CR1000 sn 23865 on the new tower set up at the Twitchell Rice site. | |
| 2012-05-07 | 4993 | CFM100 | Removed | Removed from the Twitchell tower. No longer needed - data being collected by Li7550 box | |
| 2012-01-17 | AIU-0397 | LI-7550 | Installed | Interface LI-7500 | Installed with LI7700 sn TG1-0211. Connected to the CR1000 by SDM. This box came with LI7700 sn TG1-0155 and is not CO2/H2O enabled. This means the SDM interface provides the 7700 data. |
| 2012-05-07 | AIU-0397 | LI-7550 | Removed | Interface LI-7500 | Removed from the Twitchell tower. Replaced with 7550 sn AIU-0614 and 7500A sn 2150. |
| 2012-05-07 | AIU-0614 | LI-7550 | Installed | Interface LI-7500 | Installed on the Twitchell tower with 7500A head 2150 replacing AIU-0397. The eddy system was reconfigured to start collecting data on this 7550 box. The CR1000 and older model 7500 head and box were removed. |
| 2012-09-06 | AIU-0614 | LI-7550 | Removed | Interface LI-7500 | Removed from the Twitchell tower with head 2150. Replaced with AIU-0674 and 2176 head. This box would enter a reboot cycled when I tried to swap heads. It will be tested in the lab. |
| 2013-01-03 | AIU-0650 | LI-7550 | Installed | Interface LI-7500 | Istalled on the Twitchell Rice tower to replace AIU-0674 for repair of the condensation problem. |
| 2013-11-21 | AIU-0650 | LI-7550 | Upgrade | Interface LI-7500 | The firmware of the 7550 box was upgraded from v6.5.2 to v6.5.5 to fix bugs with the USB memory overwrite and synchronizing the 7700 clock. |
| 2014-03-07 | AIU-0650 | LI-7550 | Upgrade | Interface LI-7500 | Updated the 7550 firmware from v6.5.5 to v7.0.1. Improved interface, support for SmartFlux, bug fixes. |
| 2014-10-02 | AIU-0650 | LI-7550 | Upgrade | Interface LI-7500 | Updated the 7550 firmware from v7.0.1 to v7.3.0. Fixed bug that can cause the instrument to restart unexpectedly, added 7700 data to interface can view/log power Vin, other minor bug fixes. |
| 2016-04-13 | AIU-0650 | LI-7550 | Upgrade | Interface LI-7500 | Updated the 7550 firmware from v7.3.0 to v8.0.0 skiping version 7.5.0 Relevant 7.5.0 changes: Main Window is now resizable, Added serial number entry for sonics, Help update, Fixed timeout when saving config files Relevant 8.0.0 changes: Separate bandwidth settings for analog inputs and gas channels, Detection of new RS instruments, Additional calibration coefficients, Added sonic software version entry, Added chopper temp logging |
| 2017-04-10 | AIU-0650 | LI-7550 | Installed | Interface LI-7500 | Added to the Vaira eddy tower for the Ameriflux inter-comparison and the transition to newer LI-7500A eddy systems. |
| 2012-09-06 | AIU-0674 | LI-7550 | Installed | Interface LI-7500 | Installed on the Twitchell tower to replace sn 0614 that was having trouble accepting new heads. sn 0614 was removed to the lab for observation. Head 2150 was removed for calibration and head 2176 was swapped in. |
| 2013-01-03 | AIU-0674 | LI-7550 | Removed | Interface LI-7500 | Reomved from the Twitchell Rice tower for repair of the condensation problem, replaced by AIU-0650. Heads swapped for calibration at the same time. |
